Broad selection of high-quality materials for plastic injection molding

We leverage a range of top-of-the-line injection molded plastics to create parts with the exact properties you need.

Polycarbonate (filled or plain) Polycarbonates are thermoplastic polymers whose chemical structures contain carbonate groups. They are tough and strong materials that are easily thermoformed, worked, and molded.
Polyolefins This type of polymer is formed from a simple olefin. For instance, to get polyethylene or polypropylene which are polyolefins, we need to polymerize olefin ethylene or olefin propylene.
ABS Acrylonitrile butadiene styrene (ABS) is a thermoplastic polymer with the temperature for glass transition around 105°C. It’s an amorphous terpolymer produced by polymerizing acrylonitrile and styrene in the presence of polybutadiene.
Polyacetal Also known as polyoxymethylene, polyformaldehyde, and acetal, it’s an engineering thermoplastic used by plastic injection molding companies to produce precision parts that require low friction, excellent dimensional stability, and high stiffness.
Rubber Natural rubber, also known as latex, caoutchouc, caucho, Amazonian rubber, or India rubber contains isoprene polymers with slight impurities of other organic compounds and water.
Nylons Nylon represents a group of synthetic polymers based on semi-aromatic and aliphatic polyamides. It’s a silky thermoplastic material and can undergo melting processes to form shapes, fibers, or films. It comprises repeating units connected by amide links which is similar to protein peptide bonds.
Acrylics Acrylics, acrylic glass, or polymethyl methacrylate, also known under trade names of Acrylite, Crylux, Perspex, Plexiglas, Perclax, and Lucite is a transparent thermoplastic typically used in the form of a sheet as a shatter resistant and lightweight glass alternative.

Unveiling our high-precision injection molding process

Our team will adhere to your requirements and work closely with you to create the parts that meet your desired specifications. With years of expertise, we’ve created a streamlined process that guarantees optimal results, from mold building to shipment:

professional plastic molding manufacturers

  • We’ll review your plans or create new ones, design plastic molds, and set the costs, budget, and schedule.
  • We have the capacity to provide low-volume, low-cost injection molds for prototypes that you can test and evaluate.
  • After creating an adequate mold approved by you, we move on to manufacture the parts.
  • Carefully selected resin pellets undergo the melting process, injecting them into the mold cavity, and left to cool and solidify.
  • When solidification is finished, plastic parts are ejected from the mold.
  • If necessary, the parts can undergo further finishing processes.
  • During and after the injection molding process, and before shipping the components to the client, the parts go through thorough quality inspection.

Frequently Asked Questions

What is plastic injection molding?

It is a manufacturing process where molten plastic is injected into a mold cavity at high pressure. Once inside the mold, plastic cools and solidifies, taking the shape of the mold. This versatile method is widely used by plastic injection molding companies near you for producing intricate and precise components in large quantities. It’s an efficient technique that can serve various industries for creating a diverse range of plastic products.

How do you inject molded plastic?

The process begins by heating plastic resin pellets until they become molten. This molten plastic is then injected into a mold cavity under high pressure using a machine for injection molding. After cooling and solidifying within the mold, the part is ejected, resulting in the desired shape and configuration.

What plastic can you mold?

The process of custom plastic injection molding is compatible with a wide range of plastics, including thermoplastics like polyethylene, polypropylene, and polystyrene. It also works well with engineering plastics such as ABS, PC, and nylon. The versatility of this process allows plastic injection mold manufacturers to produce diverse components for various applications.

How much does an injection mold cost?

The cost can vary based on factors like complexity, size, and material. High-precision injection molds with intricate designs may incur higher costs. Plastic manufacturers near you often assess specific project requirements to provide accurate quotes, ensuring the mold meets the desired specifications for efficient and cost-effective production.

What does a plastic manufacturing company do?

It specializes in the production of plastic products using the process of custom plastic injection molding. This is a highly efficient method that is widely used for manufacturing various products across industries.

What is the best plastic for injection molding?

The choice depends on the specific application and requirements. Commonly used materials for general purposes include polyethylene, polypropylene, and ABS, while engineering plastics offer enhanced strength and performance. At our plastic injection mold company, material selection is crucial for achieving desired characteristics in the final product.
