Many rapid prototyping processes are great for testing form and fit, but often times there is simply no substitute for testing with the real injection molded parts and material. When your production tooling won’t be ready for months, injection molding is a great way to receive parts quickly and inexpensively. We can use various materials and techniques to create bridge tooling for prototype testing and evaluation.

At Schmit Prototypes, our in-house technologies provide complete tool making capability and immediate support for product modifications. Injection molds can be produced in cast steel, aluminum, P-20 or high-grade tool steel. Aluminum can be used if your volume requirements don’t justify the higher cost of steel tooling. Aluminum can be very cost effective.

We can deliver prototypes and short-run production engineering-grade thermoplastics fast, reducing your time to market. Our variety of press sizes allow us to meet your plastic injection molding needs from 10 to 100,000 parts.

Injection Molding

Overview:

Injection molding is a manufacturing process in which plastic material is forced into a mold cavity under pressure. Pelletized resins are fed into the injection molding machine, as well as any colorants required. The resins and colorants are introduced into an injection barrel where they are heated and melted. The material is then forced into the mold cavity where it cools. Once cooled, the part can be removed from the mold cavity.

Injection Molding Applications:

Injection molding is the most common method for part manufacturing and is ideal for producing multiple identical parts.

Injection Molding

Injection Molding Materials:

  • ABS
  • Nylon
  • Polycarbonate
  • Ultem
  • Polypropylene
  • Acetal
  • Nylon
  • And many more

Finishing:

Little to no finishing is required on injection molded parts because the desired textures and finish levels are applied to the mold cavity.

Part Deilvery:

At Schmit Prototypes the average delivery time for injection molded parts can vary greatly depending on part geometry, cycle time and volume. Please contact one of our project managers for more information on timeframe.

Why Injection Molding?:

  • Injection molding allows for repeatable high tolerances
  • A very wide range of materials can be used
  • Minimal scrap losses
  • Little need to finish parts after molding
