Our Automotive Plastic Injection Molding Workflow

Working as one, our team of engineers, manufacturing experts and product designers creates plastic pieces and auto parts that work for your requirements. Initially, you and I will decide together on what the product is, how it will be used, how many are required and all other important aspects. With this information, we can give the best advice on which thermoplastic is recommended and choose between automotive thermoforming or injection molding.

After all the information is confirmed, we print a 3D model of your product and use high-tech technology to create a prototype. At this point, our staff helps you enhance the design, address problems and study options for improving the product.

With prototype approval, we proceed to tooling and carefully plan injection molds to shape your product in the best way. To cope with the need for high accuracy in automotive plastic injection molding, we could create temporary tools that test pressure, check for issues in the mold and guarantee that the result matches the prototype.

The injection molding process begins after the final mold has been made and is heated to its melting point. Then, plastic material is forced under tremendous pressure into the mold to ensure everything is shaped exactly. Once the plastic piece has cooled, it is thrown and goes through added routines such as assembly, painting or sanding.

Injection Molded Interior Components for Automobiles

For the lively automotive industry, we focus on producing many injection-molded interior parts. We perform interior component projects for the leading automakers, making use of our ISO and IATF-certified sites. Because we have lots of experience as an OEM and Tier 1 automotive supplier, we design and supply both interior and exterior trim parts. Items made of plastic for car interiors (e.g., glove compartments, interior pillar trims, door handles, air vents, center consoles, roof units and so on) are found in our portfolio.

Injection Molded Exterior Automotive Components

Injection molding is highly successful for manufacturing a wide selection of external auto parts. With the help of automotive OEMs and Tier 1 suppliers, our team of experts makes sure to understand all technical details and perfects the production of exterior vehicle parts. We are a trusted company making plastic injection molded parts for cars such as mudguards (fenders), wheel arches, grilles, sensor mounts, floor rails, trunk trims and covers for both front and rear parts, as well as bumpers, exterior door trims and door panels. A lot of vehicle models around the world incorporate our plastic parts.

Why Opt for Custom Automotive Plastic Injection Molding?

Advantages in today’s engineering-grade resins have led companies in the automotive industry to use plastic parts instead of traditional metal or ceramic ones. They can handle very high temperatures and a lot of friction; besides, they are not heavy and strong. Choosing plastics instead of metal or ceramic materials enables cars to become lighter, makes production less costly and reduces the chances of scratches and impacts.

Because producing automotive parts using injection molds takes a longer development time, the process is still popular for its benefits.

A Lot of Incoming Inquiries
To handle the needs of mass producing plastic parts for cars, we choose strong materials such as heavy steel, aluminum or beryllium-copper alloy. By making parts on the same mold, you can cut down the cost for every single plastic part, even if you have only one big order or many.

Quick Manufacturing
When the automotive injection mold is finished, the process can be carried out quickly. Production waste is almost zero which means the plastic pieces can be taken out of the mold and used as designed.

Advanced Designs for The Critical Parts
Parts in cars made from plastic may have edges above the surface, uneven thickness, sharp angles and fine details. Something that is hard to do with other manufacturing techniques can be done precisely with the use of injection molding.

Minuscule Parts
Even though both methods can make large and small items, injection molding is a better pick for knobs, dials and buttons. It is possible because of multi-cavity molds which increase the speed of production.

Your Trusted Partner for Automotive Molds and Parts

Regular tasks for automotive producers are to focus on safety, better vehicle fuel use and environmental efforts.

ZCmould provides our clients with fairly priced plastic items and plastic injection molds made right here at our facility.

The plastic components we have designed and improved perform very well. This is mainly due to the low weight they offer which is important as electric vehicles increase in popularity and losing weight matters a lot.

Your Partner in Automotive Part Design and Material Selection

In the automotive field, injection molded plastic is often exposed to very high pressure. Some designs are so detailed that tolerances can be as small as 0.001 inches nowadays. The areas underneath the hood experience severe changes in performance, different chemicals and high and low temperatures. That is why designs and materials must be tough enough to endure the hardships of offshore workplaces.

Resins are made now for many applications and they are designed to supply several properties like strength, flexibility, the ability to withstand high and low temperatures, corrosion resistance and UV protection. ZCmould experts in material science and injection molding assist OEMs in choosing the plastic that will perform best without wasting money. This knowledge is always clear from the design and manufacture of delicate vehicle braking, cooling, fuel delivery and powertrain parts.
