To form a correct idea about the calculation of the custom injection mold price in China, we have made a convenient infographic with numbers for you:

Prices of custom injection mold

The costs of tooling are different. The mold life depends on the size, configuration, and steel quality of the molds. Sometimes, the injection mold is sufficient for the production of more than 1 million shots. One injection shot can produce up to dozens of products. We built a mold with 32 cavities a few years ago.

This means that the mold can produce millions of items. After the mold has been worn out, it can be restored. The cost of restoration is usually no more than 25% of the original cost. Mold production time is about one month to two months.

Material Selection for custom injection mold in China

Services for the manufacture of plastic products are understood directly as services for the molding of plastics. Moreover, this means that the price does not include the cost of material and tooling. It should also include ALL necessary additional services, such as commissioning, configuration, test run, processing, and packaging of the final product.

The use of plastic in the industry

Plastics are raw materials that are widely common in various industries. The main property of this material is its ability to take any desired shape. All this explains the popularity of raw materials in the production of a huge number of products.

Why is plastic so in demand by modern manufacturers?

The relatively low price in China of raw materials reduces the cost of the final product. Moreover, in a market economy, its wide application is a weighty argument. The main industries that use plastic:

When creating expensive complex devices, the ability to use high-quality, but inexpensive materials is a real find.

It was the replacement of most unloaded metal parts with plastic ones that made most of the once expensive machines and devices available to the average user. Moreover, almost all equipment, tools, auxiliary parts, all kinds of components could be made from plastic material.

Plastic is common in the medical industry to make components

Plastic is common to make components for medical instruments and devices, containers for storing medicines, and ampoules. In surgery, plastic heart valves, prosthetic limbs, and teeth are common. The handles of crutches and devices for people with diseases of the musculoskeletal system are also made using this material.

They are also common as packaging for seed

Agriculture. Here, polymer films have found the widest application as a covering material for greenhouses, fruit, and grain storage facilities. Moreover, they are also common as packaging for seed, in the creation of irrigation and cultivation facilities, garden tools.

The necessary outlines and dimensions are given to plastic by molds. They are a container where the molten raw material pours, where it cools down, acquiring the necessary hardness.

An efficient and widely common method for all kinds of plastic items

Plastic items are common almost everywhere – in medicine, manufacturing, electrical engineering, construction, shipbuilding, and automotive.

How does the plastic injection molding process work?

The whole process of injection molding can be conditionally divided into two stages: preparatory stage and main stage.

1. During the preparatory phase, a 3D model of the product comes according to the customer’s descriptions, photographs, or drawings. Next, a prototype of the future finished item is possible to develop. Based on the CAD model, after checking the prototype, a plastic injection mold is designed.

At the preparatory stage, testing of the prototype and the first copy of the product is carried out, this is necessary in order to identify possible inaccuracies and flaws in the designed 3D model or injection mold. 

Products depend on high-quality and accurate preparation

The quality and service life of products depend on high-quality and accurate preparation. Our experts will competently advise on the choice of the necessary raw materials for the creation of a particular product.

2.  The main stage of the injection molding process includes the following points: plastic injection, molding & mold cooling, product ejection.

Calculation of the cost of injection molding services

When calculating the cost of injection molding in China, the following factors are taken into account:

The complexity and parameters of the product

Order volume: the higher the volume, the lower the cost of one product.

Advantages of the method

1. Using the injection molding method, you can get a part of any size and complexity. The design of the manufactured mold takes into account the smallest details, many bends, and holes of the planned product.
2. All aspects of the molding parts to produce are taken into account during the preparatory phase at the time of testing.   
3. Designed before production, the high-pressure injection mold has great strength. However, do not lose sight of the fact that it has a certain resource, which is selected based on the requirements of the client. This resource is limited by the amount of closing/opening of the form.
4. The presented method is successfully common in large-scale production.

The practical significance of injection molding

Thanks to the high-pressure injection molding method, almost any plastic product can be made:

• Kids toys
• Plastic packaging, caps, caps, etc.
• Enclosures for electronic equipment
• Enclosures for medical equipment
• Component parts for the automotive industry, etc.

Injection Molding technology for the production of plastic products

To date, the most popular method for the production of plastic products is injection molding. It assumes the possibility of automating the process, gives excellent results in a short period of time, and does not require any additional work with the produced parts.

Usually, the resulting parts can be recycled, so plastic injection is also environmentally friendly.

Injection Molding technology includes several operations

First of all, it is necessary to dry the thermoplastic polymer granules, which are the main material for obtaining a new product. The granules should not contain more water than the production requires, so their drying is required.

Thermoplastic polymer granules

Before injection molding, the pre-processed material enters the receiving hopper of the TPA (injection molding machine) with the help of an operator. Further, the machine itself works with the raw material. It guides the pellets into the melting screw, and then, with a special piston and high pressure, the raw material will be quickly poured into a mold. Now the mold has only to cool down so that you can get a molded part.

How does an injection molding machine work?

The main parts of the custom injection molds are the plasticizing unit and the clamping unit. Moreover, the work in them is provided by hydraulic actuators, an electric motor is responsible for the pressure. Numerical control (CNC) is common to form a specific product.

This mechanism monitors the fulfillment of the established characteristics during the process and regulates various external devices (for example, the same hydraulic drives, electric drives, heating elements, etc.).

The maximum possible injection volume

Of course, in each specific case, it also depends on the capabilities of the molds. However, there is a limiting possibility of the apparatus itself – one can simultaneously serve a larger number of injection volumes, and the other a smaller one. The unit of measurement is grams or ounces. Although we are talking about volume, in fact, it is a mass of material.

The characteristic of custom injection molds

The characteristic refers to the injection unit and means the constant value required to influence the melt during the entire working cycle. Moreover, distance from one guide plate of the machine to another. That is the maximum width of the molds common.

The lack of one characteristic of the machine is easy to make up for by an excellent indicator of another. For example, to increase the pressure, it is enough to reduce the screw radius. However, in this case, the maximum allowable injection volume will also decrease.

At the same time, an increase in pressure will cause a corresponding increase in the opening force of the custom injection molds. It is not scary if the injection molding machine is able to enhance the closure. Otherwise, you need to replace the injection machine with a smaller one.

Injection molding methods

Different methods are common for different injection molding tasks. The most common of these is injection. It provides a rapid injection of material into the mold under high pressure. The intrusion method is common for molded parts with thick walls, the material enters the mold in the form of a spinning “worm”.

Injection molding is advantageous to use in the manufacture of large parts. Moreover, multi-layer custom injection mold in China involves the production of multi-colored parts from several materials, etc.

What plastics can be common?

Injection molding produces plastic products that are able to melt again. These are:

• Polyethylene
• Vinyl plastic
• Acryloplast
• Polyamide, etc.

Industrial plastic is one of the main materials common in production in top injection mold manufacturers in China from the most diverse segments around the world. Versatile polymers are able to meet varied needs with great quality.

The ease and speed of production

Among the main reasons that lead to the adoption of plastic in industrial processes is the ease and speed of production. Using molding techniques, it is possible to mass-produce in record time, when compared to other raw materials.

This practicality, however, can only achieve by carrying out a series of steps that ensure the suitability for different projects and a quality service capable of meeting the needs.

Below, we present you with these steps, increasing your knowledge about the thermoplastic molding process. You can make even more assertive decisions and stand out from your competition.

The best top injection mold manufacturer in China

The design chosen for your part or product is essential to achieve a satisfactory molding, paying attention to the following factors:

• Thickness of the mold walls – which must be constant throughout the part;
• Eliminate unnecessary parts – whenever it is possible to eliminate components without any loss to the design, eliminate;
• Adjust the size – the measurements must be adequate to avoid distortions and loss of capacity of the parts. If necessary, divide the project into more parts;
• Respect the thickness of each material – different plastic resins have maximum and minimum thicknesses to achieve the results, respect the characteristics of each material;
• Take care of transitions – eliminate sharp transitions in the design in top injection mold manufacturers in China that cause tension in molded plastic;
• Beware of Straight Corners – Straight edges weaken parts due to molded tension common by resin flow. Prefer to work with curves;
• Beware of thick sections – thick sections with screw holes can cause sags and voids in your part;
• Be careful with the fillets – count on support resources for the pieces in your design;
• Be careful with the ribs – the ribs must not exceed 60% of the wall thickness, under the risk of causing sags;
• Beware of Vertical Walls – Vertical walls should be as sloped as possible to facilitate mold ejection.
• Prefer cavities – cavities are a better option than ribs as they allow for the maintenance of thickness in the part.

Sketch (as much as possible):

Even with all the care in the top injection mold manufacturers in China. It is important to make more than one design draft, always looking to correct and improve. This is an important measure that helps to achieve maximum quality and efficiency.

The more the thermoplastic injection partner understands what it needs. The better it will be able to offer solutions that meet its needs, bring productivity gains, and reduce costs.

Top Injection molding manufacturer for your product

Each product that passes through the thermoplastic injection molding machine is unique in its characteristics and intentions. It is important to remember that there are a number of established solutions that are easy to be adopted by your top injection mold manufacturer in China.

Talk to your supplier and check the best suitable options for your parts, in order to offer the best resistance and suitability for your goals. This is an important detail that directly impacts the final result.

Check for logos or texts on industrial plastic parts

It is common for companies to want to identify their components. On plastic, this is easy to do during molding and offering textured identifications.

The texts and logos that will be applied must count in the design. They will be part of the mold common in the top injection mold manufacturer in China.

Check for thin edges in injection molding:

Edges can be a challenge to achieve quality industrial plastic molding. When thin, they restrict flow, leading to breakage and other handling defects.

It is important that all these details are checked with trained professionals. Following are the suggested changes.

Check for pieces that fit together:

Having identical parts that fit together and are complete is always a good solution when we are talking about plastic injection.

In this way, it is possible to use the same mold, generating savings and increasing the productivity and speed of the process. It is always necessary to verify the existence of these components to achieve these effects.

The expectation from injection mold manufacturer to meet all needs

When choosing the top injection mold manufacturer in China, the expectation for components, and products with industrial plastic, is to have a result that is able to meet all needs.

For this result to be possible, it is essential to study the tolerance and resistance of the project, as well as the potential resins to be common. This study must be done before the molding begins, avoiding waste of resources.

Choose the suitable material

After taking all the care with the design, paying attention to critical points that can compromise the entire final result, it is time to choose the resin that will be common in the injection of thermoplastics.

There are many top injection mold manufacturers in China found on the market today that have different characteristics, which must be taken into account considering the design, functionality, and expectations of manufacturers simultaneously.

Choose dyes

Industrial plastic welcomes most colors, and these specific dyes are common that do not change the composition or structure of the material and guarantee results for the entire life cycle of the product.

When the preference for colors that are outside the basic palettes, it is possible to achieve the desired result through studies and mixtures of different tones, remembering that the amount of dye applied and how it will be manipulated vary from resin to resin.

Choosing resin additives:

Although plastic resins are able to meet most of the needs of industries, in some cases, it is necessary to reinforce characteristics, such as chemical and physical resistance, malleability, among others, through the application of additives.

Among the main additives common, the following is easy to highlight:

• Glass fibers;
• Carbon fiber;
• Minerals;
• Teflon;
• Aramid wound;
• UV inhibitors, etc.

Industrial plastics: the best choice for your product

If plastic is one of the main raw materials in the top injection mold manufacturer in China today, this is due to its stupendous versatility and quality to meet the most varied objectives and needs.

For this, however, the material needs to be correctly worked, not only counting on suitable molding machinery but also making adjustments in designs, choosing the right resin, and using other products to adjust the final result, such as dyes and additives.
