Fathom offers a variety of materials for injection molding, including amorphous plastics. By using the latest injection molding technology, Fathom offers its customers high-quality parts. We can meet the requirements of your time-sensitive, highly complex, high-precision and short production run related job.
Amorphous plastics are some of the most used polymers in manufacturing. Amorphous plastics have good dimensional stability and excellent impact strength and are less likely to warp. Examples of amorphous plastics include polystyrene, polycarbonate, ABS and more.
Amorphous plastic is ideal for injection molding applications. In their solid-state, most amorphous polymers are transparent, making them perfect for parts in the optical industry. Amorphous plastics can be used with solvents and adhesives. Plastics within this category are less susceptible to shrinkage.
Amorphous and crystalline plastics have distinct differences. Crystalline polymers have a specific structure, while amorphous plastics have no specific arrangement or pattern. The lack of pattern leads to amorphous plastics’ lower density and lower chemical resistance. Amorphous plastics are softer than crystalline polymers and easier to injection mold.
Following injection molding, the part transitions to the finishing stage. Finishes can add physical properties to a part or may change its appearance. Here are some of the finishes 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 |

A: Yes, Fathom offers injection molding services.
A: Injection molding is a manufacturing process commonly used for plastic parts. Molten plastic is injected into a two-part mold using high pressure during injection molding. Once the part has cooled inside the mold, it is ejected. The part may or may not require a secondary finish.

A: Amorphous plastics have good dimensional stability, are less likely to warp and have excellent impact strength.
A: Yes, some plastics are amorphous.
A: Amorphous polymers include polystyrene, polycarbonate and ABS.
A: Amorphous plastics do not follow a pattern or structure like semi-crystalline polymers. Amorphous plastics have lower density and less chemical resistance than semi-crystalline polymers.
