5 Proven Automotive Injection Molding Tips

Introduction of Automotive injection molding

Having competitive automotive injection molding plants is not a goal for the near future. It is a necessity for the present. If we want to be at the forefront of world standards, it is the ideal time to break paradigms.

It is to implement an action plan so that their injection plant has profitable products and increases competitiveness.

1. Invest in a robust product and mold design phase:

The problems that are easy to solve at this stage are key to a successful and profitable project. For this, we must have a team trained not only in aesthetics and user experiences but also in product design.
Automotive Injection Molding

Hence, we can create automotive injection molding easily. This concept is known as design for manufacturing, and for us, it is equivalent to design for injection.

This may mean the survival of our product through the time after its launch. Despite the design rules being described in the mold design books, companies continue to see manufactured products. This violates the rules of an injectable product design, and this situation is recurrent even in large consortia businesses.

2. Partial or integral solutions for automotive injection molding

We are in the millennial era where it is possible to use different technologies such as:

  • Prototyping
  • Simulation

Prototyping allows having model pieces where there is an exchange of meanings, customization, and decision-making for shape changes.

For its part, simulation and parallel advance in computational capacity provide a wide range of software developers. In this topic, we say that there is still a lot of fabric to cut from, but we can review that in a future edition. There are no good or bad software packages.

3. Operational functionality of the product

If you are part of a company that markets molded products, the product design must be robust enough. You are comfortable with the risks it provides to the automotive injection molding maker. For this reason, its viability must come not only on the prototype but should also carry out an exhaustive finite element analysis.

Similarly, it determines the operational functionality of the product. This should move by a process simulation where it is possible.

Essential to have a partner that supports you

Quantify your product in productivity, material, and quality before passing it to the mold designer. It is essential to have a partner that supports you throughout the production chain. It not only allows you to simulate the product but also to perform complete mold analysis.

All interacting materials (metal, plastic, and water) and process square as if they were at the foot of the machine. The application of these technologies can represent an anticipated saving of approximately 27% in raw materials, a 50% reduction in cycle time, and 20% in design iterations. Have you already done the math?

4. Temperature control – formula five:

It is still believed that the only variable of thermal control in an injection process has to do with nozzle and water temperature (either chiller or peripheral equipment). However, other hidden variables affect the thermal history of the polymer from the pellet state until the product is expelled.

For this reason, it is transcendental to break down the known and the unknown in this matter. For both technologies described in point two, it is important to be clear that nipples, screws, nuts, plugs, etc., are consumable components and large accumulators of deposits, therefore, with maintenance, new ones should be installed.

5. Automotive injection molding

At the end of production, the automotive injection molding must be free of any adhering plastic residue, regardless of the type and quantity of material. For this, the chemical attack must be common which, depending on the aggressiveness of the polymer, will be concentrated.

For this idea, it is also recommended to remove the lubricant residues from the moving side of the mold with a degreaser.

6. Hot Runner System for Automotive injection molding

In summary, after a demanding productive run, the thermocouples, cartridges, and heating bands should be checked with a multimeter to compare with the datasheet that is within the normal range.

This is a very specialized system that must be supported by the system supplier since assembly and maintenance training should be carried out with the delivery of the mold.

7. Slide Guides Automotive injection molding

In the moving half, the guides require care. On the one hand, it is important to clean with acid and resin-free lubricants, and, on the other, to check the cylinder seal level in case of having hydraulic actuators on the slides and inserts.

8. Contact Between Nozzle And Material Inlet To The Mold

This area is subjected to high loads during operation. There is a free space where the material can flow and relieve pressure, however, this burr must not exceed the limits; If this happens, the area must be rectified or the temperature profile configured in the machine must be reviewed.

9. Proper Mold Handling

The problem of damage provided to the Automotive injection molding lies especially in operating and assembly errors, which in the same proportion is a problem attributed to poor communication between the design and maintenance team.

Everything starts from the fact that each mold is unique and it is not correct to generalize the maintenance process. It must start from a general protocol, but each mold must have its resume documented and the workshop must have adequate equipment that allows the mold to be handled correctly.

10. Automotive injection molding Instrumentation

Automotive injection molding allows comfortable opening, turning, locking, and closing of the mold, reducing the risk of systematic errors.

The production documentation is useful to find out that there is a problem, but the information available will be much more effective if we have a plant that applies the concept of Industry 4.0. This is possible by implementing sensors for temperature, pressure, humidity, flow rate, number of cycles.

Conclusion

Automotive injection molding

The exact time the Automotive injection molding was open, etc. in each mold. This is the beginning of an intelligent plant. This allows establishing the cause and/or root of the problem, effective maintenance times of the mold, and making correct decisions in real-time.

9 Reasons to use Automotive Injection Mold for Smooth Product

Introduction of Automotive Injection Mold

As in all industries, plastic Automotive Injection Mold has its types of defects that can damage or damage the part. It is very important to work with companies that understand and have the quality control and non-compliance skills needed to avoid defects and inaccuracies in production.
Automotive Injection Mold

Not all defects occur in the same way, so it is important for you, as a client, to understand the reasons for their occurrence. Today we are considering “divorces”, a typical cosmetic defect that may indicate problems with plastic or with the production process.

What is a singularity in plastic injection molding?

Divisions in injection molding are determined by the stripes that occur along the entire surface of the formed part. Most often silver is a reaction due to water entering the plastic during the heating process inside the mold. This is due to the humidity in the places of supply of plastic, which when heated.

In the middle turns into steam. Then it turns into tiny gas bubbles, which penetrate the plastic during its injection, leaving a silver pattern on the surface of the finished part.

 

What are the main causes of divorce?

The main problem with this Automotive Injection Mold defect is moisture, but how exactly does moisture get into the process? Although plastic resins/plastics that melt to form parts are often considered waterproof, it is important to remember that many of these plastics are easy to absorb or covered with moisture at various points in the process.

They may come from the manufacturer already containing moisture or receive this moisture during transportation, storage, or preparation for production. The plastic needs only a little moisture to cause the highlighting effect – ie the appearance of stains.

Elimination of Automotive Injection Mold defects in details

Whether you have already dealt with stains or just want to avoid them in the future, it is important to remember to protect both the material and the equipment from moisture. Here is a list of specific recommendations to avoid this most common problem.

Avoid degradable plastics

If plastics remain heated for too long or at too high a temperature, they can begin to break down and decompose, releasing gas and moisture, causing spills. Avoid too much re-grinding: Too high a re-grinding rate – the use of reusable thermoplastics – sanded after use before.

It can also become contaminated with moisture. Eliminate inaccuracies in the feed rate and the design of the mold: if the plastic melting nozzle is running at too high a speed, or if the Automotive Injection Mold hole is the wrong size, it can also create spray effects – stains.

There are several steps to getting a finished plastic product.

The variety of plastic parts that we encounter every day – is very large, and every day they become more and more. Plastic products are common by more than 90% of the world’s population, in this regard, the processing of plastics is developing very rapidly, there are new technologies for plastic casting. A large niche in this area is occupied by injection molding of plastics with the help of a tool called – a mold.

  • Detail design.
  • Construction of the mold according to the drawings.
  • Making a mold.
  • Checking the efficiency of the forming equipment.
  • Product casting.
  • Product design

To create a 3D Automotive Injection Mold model, such important factors as:

All stages of mold part development are done using software (CAD). The use of CAD reduces the time spent on development, reduces the percentage of design errors in the design of the Automotive Injection Mold. The designer of equipment (molds) makes a mathematical design of 3-d model on the information given to it from the customer.

  • product individuality
  • material characteristics
  • product part optimization

The result will be a model and a drawing of the product. It can be common to evaluate the product and its forming equipment.

Design of Automotive Injection Mold

When the development of the part is completed, the design engineer begins cooking to design the mold. The choice of components for molds is of great importance. The stability of the form, quality of a forming surface of the form, ability to give of processing of working parts, and quality of the future plastic product depends on the material.

Steels with a hardness of 30… 32 HRC are required for the correct operation of the mold, they can be common for the manufacture of Automotive Injection Mold parts of the mold without heat treatment, these factors will significantly reduce the time for the manufacture of equipment.

9 reasons to use Automotive Injection Mold

Nowadays, more and more often molds come from corticosteroids (hot runner systems), and there are reasons for this. The use of corticosteroids has many advantages. Including:

  • casting time costs are reduced.
  • reduced pressure in the mold.
  • improved product quality.
  • reducing the cooling time and obtaining the finished product.
  • lower cost of the product.
  • There are also disadvantages of using corticosteroids
  • price
  • difficulty in servicing
  • there are problems if you work on secondary material.

The Structure of Automotive Injection Mold

The thermostatic structure of the mold must create the correct distribution of the thermal sides of the molding levels of the mold and be separate to reduce the time spent on the manufacture of the part. The final work of the designer to develop an Automotive Injection Mold will be a 3D model of the form, and a set of technical documentation.

The 3-D example of the forming planes come by the designer is common for the writing of programs and processing of surfaces of metal on the ChPU machine. At the end of the creation of products following the design, documentation is assembled, also prepared for testing the mold.

  • general information about hot runner systems
  • res-forms with a hot-runner system for processing thermoplastics

Conclusion Automotive Injection Mold

After installing the mold on the thermoplastic machine, we test the mold. Our purpose is to collect information for future changes and corrections of surfaces, gutter, and ventilation systems, after these actions the mold comes into operation.

The final stage of manufacturing the part – Automotive Injection Mold. At this stage, it is important to adjust the process of casting plastic parts under pressure.

What is the cost of Cavity-Lifter Injection Mold?

Introduction of Cavity-Lifter Injection Mold

The production of a perfect part begins with the Cavity-Lifter Injection Mold. Designing a shape is usually time-consuming and requires great precision. The process of its production often requires large funds, so the success of the whole project depends on the correctness of the drawing and the accuracy of the mold.

At the same time, if the goal of the project is to manufacture many parts with a high degree of accuracy, the production process itself becomes even more complex and complex. Plastic manufacturers usually provide information on material shrinkage and melting point and recommendations on melt rate.
Cavity-Lifter Injection Mold

Choice of plastic for the mold

The machining and casting process depends on the type of plastic common to make the part. Amorphous plastics are less free-flowing and generally less compressed than crystalline or semi-crystalline plastics, which provide better permeability but greater material shrinkage.

That is why many projects are implemented using technical composites/polymers, which give better melt and less shrinkage. Polymer shrinkage affects the design/drawing and machining of molds. The socket of the Cavity-Lifter Injection Mold must ideally accommodate/shrink the amount of material that will occur when casting the part.

Processing according to Cavity-Lifter Injection Mold standards

Using modern CAD software products, designers usually design Cavity-Lifter Injection Mold. The size of the increased tolerance depends on the characteristics of the polymers/plastics from which the part is poured. Sometimes this shrinkage is easy to correct.

By adjusting the flow of material and maintaining its appropriate level in the mold. It is important to note that any plastics and polymers can compress during cooling, even after the part has been removed from the mold. Deformation of the casting process can occur if there are jumps in temperature, pressure, fluid/material flow rate.

Accurate design work as a guarantee of high quality

Precision parts must accurately meet the standards not only for the parameters of the mold slots but also for the use of components. Similarly, we need to focus on the design of the Cavity-Lifter Injection Mold. Inlets and outlets must be in such a way as to ensure proper passage/flow of material and appropriate pressure.

The size of the inputs/outputs is also an important element. The inputs must be large enough to ensure a proper supply of material without increasing the production time (cycle). If the inlets/inlets are too small, the supply of material may not be enough to fill the mold slot or may provoke other defects in the part. The design of the mold should also provide for appropriate purge/ventilation.

Quality and costing of Cavity-Lifter Injection Mold process

Ventilation openings allow air to be released during the melting of polymers/plastics, get out of the mold. Like the situation with the outlets, the correct location of the vents plays an important role in ensuring the quality of the casting process and the manufacture of parts.

Too large holes can cause material leakage and other problems. Holes that are too small do not allow to release of the mass of air and gas that has accumulated in the Cavity-Lifter Injection Mold. Such gas residues can provoke incorrect filling of the form with material and other defects. The gas may ignite and leave traces of combustion.

The right cooling system is the key

which has accumulated in the mold. Such gas residues can provoke incorrect filling of the form with material and other defects. The gas may ignite and leave traces of combustion. which has accumulated in the mold. Such gas residues can provoke incorrect filling of the form with material and other defects. The gas may ignite and leave traces of combustion.

An efficient cooling system is an important element in ensuring a high-quality mold. The mold must maintain a constant temperature to avoid material shrinkage and deformation of the part while minimizing time cycles and maximizing output. The combination of the described elements is achieved.

Prototyping – improves the quality of the production process

Avoiding inaccuracies in the manufacture of molds and the need to recycle the Cavity-Lifter Injection Mold allows the company to save time and money in the long run. This step is necessary and requires a detailed and accurate drawing of the form, selection of polymers/plastics, and adjustment of appropriate parameters.

Setting the temperature and regulating the flow/supply of material into the form). In the event of problems with the quality of the workmanship, the development team will re-test the samples to achieve strict compliance with the standards, determining the cause-and-effect relationships of defects.

The choice of metal is the basis of high-quality mold production

The more inexperienced a player in the plastic casting market is a company, the more likely it is to use aluminum to make Cavity-Lifter Injection Mold. This material is ideal provided that the form will not be common in the long run. However, if the parts design/plan involves the use of a mold over a long period (several years).

Number of seats/sockets in the Cavity-Lifter Injection Mold

Compared to aluminum, steel withstands higher pressures throughout the production cycle and allows adherence to near-ideal tolerances. In general, most mold manufacturers recommend making a single mold for casting apart, rather than creating a multi-cell mold. Multi-nest forms are made with several places/holes for components. With the help of such forms, as a rule, produce lower quality parts, and the process itself causes more downtime due to maintenance problems. Hardened steel molds last longer to use, but require more money and longer processing. However, when such a Cavity-Lifter Injection Mold is ready, the term of its use for the production/casting of parts is quite long.

Machining of the Cavity-Lifter Injection Mold

All molds must meet the requirements and specifications provided by the customer. Fitting to requirements includes the location of cores, sockets, spouts, cooling systems, and more. Steel, which is common in the manufacture of molds, also affects the cost of the mold itself.
Cavity-Lifter Injection Mold 2021

As well as the number of sockets, the complexity of the part itself affects the cost of manufacturing the mold. This includes finishing the surface of the final part as well as the number of required threads. Details that require a clear tolerance also affect the complexity of the mold.

Conclusion

Cavity-Lifter Injection Mold

Some manufacturers of molds also engage in the manufacture of parts. This combination of two tasks: the manufacture of the Cavity-Lifter Injection Mold and the casting of the part allows you to cover the cost of manufacturing the mold. Typically, manufacturers that provide a full range of services include part.

Or all the cost of making a mold in the cost of contact. Such manufacturers will be able to depreciate the cost of the form in such a way as to achieve a margin (make a profit), providing the lowest level of costs for customers.
