Automotive mold

Automotive Plastic Mold from Chia

We know there are many a fashion contracted car parts, it need different parts of the rich also surprises people; And a lot of auto parts in the production of also need certain mold, so the market is need a variety of automobile plastic molds; At the same time due to the use of the car performance is most in need of various parts of the precision of coordinate, so they need auto mold is adherence to specifications.

For car production is a complex process, and that this complexity is the specific performance for the parts of the production process, but if you use the high quality of auto mold is very good, you don’t need to trouble! PURROS can not only provide people with a variety of high quality automotive mold, also can do professional production in the mold.

What is Automotive Plastic Molding?

Automotive plastic molding refers to the process of shaping plastic materials into desired parts and components for use in the automotive industry. This process involves the use of specialized molds, called dies, which are created using computer-aided design (CAD) software. The plastic, typically in pellet form, is then heated and injected into the mold under high pressure. Once the plastic has cooled and solidified, the mold is opened and the finished part is ejected.

There are several different types of plastic molding techniques used in the automotive industry, including injection molding, blow molding, and rotational molding. Injection molding is the most common method, accounting for around 75% of all plastic molding in the automotive industry. It is suitable for producing high volumes of parts with tight tolerances and fine details. Blow molding is used to create hollow parts, such as fuel tanks, and is suitable for low to medium production volumes. Rotational molding is used to create large, complex parts with a seamless, one-piece design and is suitable for low volume production.

Applications of Automotive Plastic Molding

Automotive plastic molding has a wide range of applications, from exterior body panels and trim pieces to interior parts such as dashboards and door panels. It is also used to manufacture a variety of under-the-hood components such as air intake manifolds, engine covers, and transmission parts.

One of the most significant benefits of using plastic molding in the automotive industry is the ability to create complex shapes and designs that would be difficult or impossible to achieve with traditional manufacturing techniques. Plastic molding also allows for the creation of parts with varying thicknesses and strength levels, which can be tailored to meet the specific needs of each application.

In addition to its design flexibility, automotive plastic molding has several other advantages over traditional manufacturing methods. It is lighter in weight, which helps to reduce the overall weight of the vehicle and improve fuel efficiency. Plastic parts are also more resistant to corrosion and can withstand extreme temperatures, making them ideal for use in harsh environments.

Plastic molding also has a lower carbon footprint compared to metal manufacturing techniques, as it requires less energy to produce and produces fewer emissions. This makes it an attractive option for automakers looking to reduce their environmental impact.

Challenges of Automotive Plastic Molding

While plastic molding offers many benefits for the automotive industry, it also presents some challenges. One of the main challenges is the high initial cost of tooling, as the creation of specialized molds can be expensive. Additionally, plastic parts are not as strong as metal parts, and they may not be suitable for certain high-stress applications.

Another challenge of automotive plastic molding is the potential for quality issues. Ensuring that the plastic is properly heated and injected into the mold is crucial for producing parts with consistent quality. Any defects or variations in the process can result in faulty parts that may need to be scrapped.

Finally, there is a growing demand for recycled and sustainable materials in the automotive industry. While plastic can be recycled, the recycled plastic may not have the same properties as virgin plastic and may not be suitable for use in certain applications.

This is the introduction for auto mold, so the rich variety of mold, at the same time to ensure the quality.

For China’s manufacturing industry, a lot of people very bullish on the manufacture of auto mold, because the automotive industry level has very good play to their strength, and now it seems that this is a industry can bring people a lot of people can’t imagine.

Among the many Automotive Plastic Mold maker in what is now the competition is very intense, therefore also make a lot of people are very like this kind of phenomenon can more arouse the vigour of the industry, in now, it seems, mold has such an environment is more and more towards an international standard.

Plastic Injection Tooling Manufacturing

plastic mold technology

Creating properly parts design and built plastic injection tooling is the most important part of any injection molded parts development. In order to build a successful high-quality plastic injection mold tooling, a comprehensive plan must be followed.

Plastic Injection Tooling Design 

If a plastic injection tooling is designed incorrectly, the penalty may be paid in part quality, injection molding tool repair costs, or longer cycle time (higher component cost) for the entire length of production needs. Because of this we focus on injection tooling design with production in mind and specify parameters up front so that design specification errors or omissions never enter into the quality/cost equation.Plastic Injection Tooling

Moldflow Analysis

we do Moldflow filling analysis during plastic injection tooling design & development to assure proper plastic flow through the tool and answer questions such as sprue size, runner size, gate size, gate position, number of gates, plastic shear level, tonnage required, weld line locations, potential air traps (potential burn marks), sink marks issue, filling time, and a host of other important issues must be analyzed before any steel is cut. This analysis is completed in the tool design phase to eliminate costly tool or part design problems that might otherwise go unnoticed until it is too late.

Plastic injection Tooling Cost

There is a wide range of parts from the very simple to the very complex with a range low to very high production volume requirements. Likewise, there are many levels of plastic tooling manufacturing companies with varying levels of overhead and capability. If a mold tool is built by a plastic tooling company with a capability level or overhead level that is above what is needed, plastic tooling cost can exceed the level that would allow a project to go forward. Likewise, if the plastic tooling company does not have capabilities needed for a complex mold, quality, price, or delivery time could suffer. This is why plastic tooling complexity must be matched with toolmaker size and capability.

We are a professional plastic tooling company in China, we make injection molding tools from small to big up to 30 tonnages, we have full plastic tooling manufacturing equipment to do all of mold manufacturing jobs in-house, this will be easy to control the lead time and quaintly of plastic injection tooling, plastic tooling we make are export to Canada, Germany, American and more country in America and Europe, The tooling components for plastic tooling can be matched correctly base on customers requirement, for Europe export plastic tooling we use HASCO tooling components, for American customers we use DME tooling components, so customers can replace any tooling components easy and fast.

Plastic Injection Tooling Warranty

We appreciate our customer’s investment and we stand by our plastic tooling. Any injection moulding tooling developed through our mold factory will have lifetime shots guarantee, plastic toolings made by our factory normally have 3 types of shots guarantee.

1. Minimum of one million lifetime shots guarantee. For this type of plastic injection tooling, we use hardened steel for cavity and core, like S136,1.2344, H13, 1.2083, 1.2343, etc, the hardness of steel is HRC 48-52,

2. Minimum of a half million-lifetime shots. For this type of plastic injection mold tooling, we use pre-hardened steel material, such as 1.2738H, P20, 1.2738HH, etc, the hardness for this injection mold tooling is HRC 33-38.

For export injection moulding tool, all of the cavity/core steel is bought from LKM (the biggest mold steel company in China), or buying the steel in Europe brand according to customer requirement.Plastic Tooling Company

3. The above two types of plastic injection tooling are for export tooling, this one is for the none export injection moulding tool, which means we will produce the plastic molded parts for the customer and ship the plastic parts to our customers, the mold tooling lifetime for this type of tooling will be no limited (as many as customer wants), the reason because we have the plastic tooling in-house, if any issue happened we can fix the tooling for our customer with no extra cost.

Moreover, if customer want us to produce the injection molding parts for them, the plastic tooling cost will be very lower, because we will never earn any profits on the injection moulding tool manufacturing, or even we can bear come plastic tooling cost, this is depending on the number of parts customer requirement, this is the best options for you to increase your market by minimum investment.

This is not the end if you choose the number three option, when you have finished number of parts production, we can return all of the injection moulding tool prices back to you, you can use this price to order plastic injection molded parts directly, of course, this is depending on the quantity of the parts you have been produced. If you want to know more about this solution? You are welcome to contact us or send your requirement for quotation, you will have our professional team to support, we offer you the best price and solution for your project, and we never share your data to any others.

Custom Injection Molding: An Overview

Custom injection molding or injection molding mold parts is a plastic part fabrication process that involves injecting stringent quality material into a mold die or cavity designed specifically for intended applications. This process allows design manufacturers to produce parts in low volumes to bulk. Generally, it’s also known as injection molding of plastics, as this process is carried out in the following manner.

The process starts by forcing molten polymer into a mold designed to match the shape of the desired product. The polymer is then cooled and solidified to form the required part released from the mold. The custom injection-molded parts or products manufacturing process provides flexibility and can be used for medium production for about a few 100s to manufacture 1000s of identical molded components at a large scale. The process is widely favored for its economic production and helps industries like automotive, aerospace, and electronics to fabricate prototypes for functional testing and enhance the aesthetics of intended products or end-use parts.

Custom Plastic Injection Molding Materials

The types of plastics used in custom injection molding are diverse, with different melting points and peculiar characteristics that can be adjusted to suit a specific application. Here are some commonly employed thermoplastic materials for manufacturing high-quality injection molded parts.

Acrylonitrile Butadiene Styrene (ABS) 

ABS is a widely used thermoplastic material that offers flexibility, low density, and good impact strength. It is unsuitable for applications requiring chemical, electrical, or UV resistance. Because of its strength,

ABS injection molding is widely used in products such as children’s toys, household appliances, and car parts.

Low Density Polyethylene (LDPE) & High Density Polyethylene (HDPE)

These versatile thermoplastics provide high tensile and impact strength and resistance to moisture. HDPE injection molding is used in consumer and industrial products, while LDPE, which is softer, is also used in similar applications. Both materials are appreciated for their high degree of durability and ability to be bent.

Polycarbonate (PC) 

PC is a crystal clear, high-gloss matte, lightweight, and yet strong substitute for glass. It is highly resistant and has high impact and mechanical strength, PC injection molding parts aer good  ideal for use in applications like bulletproof glass.

Polyamide (Nylon) 

Nylon injection molding part is a popular thermoplastic known for its electrical properties, mechanical strength, heat, wear, and chemical resistance. Because of its durability and high functional performance, it is commonly used in the medical and automotive industries for injection molded mold parts.

High Impact Polystyrene (HIPS) 

HIPS is an inexpensive, impact-modified crystalline styrene-rubber copolymer widely used in producing disposable cutlery and toys. It is non-toxic, suitable for use in food-contact applications, and appreciated for its flexibility and low price.

Polypropylene (PP) 

PP injection molding part is a tough plastic with good chemical and stress resistance and high impact strength. Due to its high melting point, it is ideal for use in the food industry, where equipment must be durable and safe for use with food products.

These materials are chosen according to the application’s needs to provide the best performance and long life of custom injection-molded parts.

Tool Design and Engineering

In injection molding, the tool is the mold or die that forms the material into the intended part. It’s in fact a negative cavity that recreates the part’s shape with the correct dimensions to allow for the material to behave as desired during injection and cooling. In the production of custom molded plastic parts, it may be necessary to use one or several tools depending on the need. Although using more tools initially raises the cost a little, it greatly reduces the cost per piece in the long run, making it economical for mass production.

These tools are located in a mold base and are a single component of injection molding machines. Mold bases are costly, so we use insert tooling that can be fitted into existing polymer molding mold bases.

Our real engineers consider the details by analyzing DFM analysis to material, and technique selection when creating custom-molded plastic components, including tool design and process optimization. They incorporate the right manifold and runner systems, molding processes, and functionalities without extraneous features, thus cutting costs on your budget.
