Prototype Injection Molding

Using the latest in injection molding technology, Fathom can produce high-quality prototypes for its customers. Whether time-sensitive, highly complex, high-precision, or short production run related, Fathom will meet the requirements of your project.

Benefits of Prototyping / /

Plastic injection molded prototypes offer many advantages. Prototyping presents the opportunity to present a design concept using a production quality part, allowing developers to gather valuable feedback while saving money and time. The prototype can also be used to test a design and uncover any material flaws early in the production cycle before moving on to a larger production run. Using injection molding, the prototype can be produced quickly, allowing a company to meet tight deadlines or be first to market.

What is Prototype Injection Molding / /

Prototype tooling is the creation of tools or molds for injection molding. Prototype tooling is sometimes called soft tooling or rapid tooling. The resulting parts made from the prototype tool are made using the same materials as the final products, which allows the developers to test a concept early in the product development process. The soft mold is made from less durable materials than steel but will still produce an accurate part.

Prototype Injection Molding Project Specifications and Tolerances / /

Incorporating the specifications and tolerances of injection molding into a design can ensure a part fits correctly once assembled. Tolerances and specifications can also influence how a part should be shaped to maximize function. The optimal tolerance for a part is critical for making a premium part at an affordable price.

Prototype Injection Molding Materials List / /

Fathom can help you select the best material for your injection molded prototype. Our materials include crystalline, amorphous, imidized plastics and more. Selecting the right material for your part is complex as each plastic has a variety of characteristics.

  • 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.

Injection Molding Finishing Processes / /

Following injection molding, a workpiece may need finishing. Finishing may be for cosmetic reasons, but some finishes can add to the physical properties of a part. Here are some of the finishing processes offered by Fathom.

SURFACE FINISH GUIDE TYPICAL APPLICATIONS
Standard No Machine Mark Tool Marks Removed Low Cosmetic
SPI-C1 600 Stone Low Polish Parts
SPI-B1 600 Grit Paper Medium Polish Parts
SPI-A2 Grade #6 Diamond High Polish Parts
SPI-A1 Grade #3 Lens or Mirror
IM-1 Light Bead Blast Need 1 Degree Draft Angle
IM-2 Medium Bead Blast Need 1.5 Degree Draft Angle
IM-3 Heavy Bead Blast Need 3 Degree Draft Angle
