Injection Molding USA – Made in America / /

Injection molding facilitates manufacturing a large volume of uniform, high-quality, and cost-effective parts. Plastic manufacturing can be a complicated process, so you need to partner with a reliable manufacturing company with comprehensive services. When embarking on the injection molding process, selecting a USA-based manufacturer makes sense. Not only will you benefit the local economy, but you will have a more direct line of communication, shorter shipping times, and higher-quality parts.

Easier to Ship Parts Domestically

Working with a US-based injection molding company will cut down lead times dramatically. It can take weeks to months to transport goods overseas. Having parts shipped within the United States will shorten delivery and lead times.

Support US-Based Companies and Workers

In addition to shorter lead times, choosing a local injection molding manufacturer stimulates the US economy, creating more jobs for Americans. Most American consumers want to purchase goods that are made in the USA. By partnering with a US-based manufacturer, you can raise the value of your business and generate goodwill with your customers.

Direct Communication

USA-based manufacturers offer a more direct line of communication and better control over the production process. If there is an issue with your part, you can correct it faster and easier by working with a local manufacturer. US-based manufacturers will also ensure your part complies with important quality and safety standards.

Higher Quality

It is no secret that goods made overseas are often inferior to parts made in the USA. While the cost of production overseas may be lower, when items are of poor quality, it will result in losses for your company as you pay for replacements and repairs. Working with a domestic manufacturing company will ensure you deliver high-quality goods to your customers that meet your high standards.

Benefits of Injection Molding / /

Injection molding has many benefits. The injection molding process is preferred when producing a large volume of uniform parts due to its high repeatability and efficiency. Depending on the complexity of the mold, a new part can be produced every 15 seconds. A single mold can make thousands to millions of identical parts. Injection molding works with various plastics, including crystalline, amorphous, and imidized. Plastics can be made in any color. As injection molding is an automated technology, the overhead and labor costs are reduced.

Injection Molding Materials List / /

Picking the right material for an injection molding project does not have to be complicated. Fathom can help you find the best match for your design. Our selection of injection molding materials includes crystalline, amorphous, and imidized plastics.

  • Crystalline Plastics: Polyethylene, polypropylene, polyetheretherketone and more are crystalline plastics. Crystalline plastics are known for their chemical resistance, strength and stiffness. They are hydrophobic.
  • Amorphous Plastics: Amorphous plastics include polystyrene, polycarbonate, ABS and more. Amorphous plastics have good dimensional stability and are less likely to warp. They are also known for offering excellent impact strength.
  • Imidized Plastics: Polyamide-imide, polybenzimidazole, and polyimide are all imidized plastics. Imidized plastics have a good load bearing and chemical resistance. They can be used for applications that will be used in high temperature environments.
  • Polyethylene (PE): Polyethylene is perfect for applications that require warp resistance and stiffness. Polyethylene is durable sustainable, and suitable for products that come in contact with food. PE is used to make everything from buckets to appliance housings.
  • Polypropylene (PP): Polypropylene is known for its heat, chemical, and fatigue resistance. Polypropylene can be combined with additives. It is flammable vulnerable to UV radiation. Polypropylene is used to produce many items including water bottles, food containers and outdoor furniture.
  • Acrylonitrile Butadiene Styrene (ABS): ABS is cost effective and easy to manufacture. ABS is known for being strong, impact resistant, and stiff. ABS is not sensitive to humidity or temperature. ABS is commonly used for appliances, automotive parts and toys.
  • Polyoxymethylene (POM): POM offers good dimensional stability, high rigidity, and low friction. Polyoxymethylene is heat, flame, and chemical resistant. POM is used to manufacture medical devices, eyeglass frames, guns, automotive parts and more.
  • Polystyrene (PS): Polystyrene is another common plastic used in manufacturing. It is known for being odorless and nontoxic. PS is used for single use products like cutlery and electronics.
