Crystalline Plastics Injection Molding

Fathom offers a wide range of materials for injection molding, including crystalline 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 project.

What is Crystalline Plastic / /

Crystalline plastics are known for their chemical resistance, high density, excellent strength and stiffness. Polyethylene, polypropylene, and polyetheretherketone are examples of crystalline plastics. Crystalline plastics are used for the manufacturing of aerospace, automotive, electrical parts and more.

Benefits of Crystalline Plastics Injection Molding / /

Crystalline polymers are commonly used in injection molding for multiple reasons. The dense structure of crystalline plastics provides them with outstanding strength, stiffness and chemical resistance. Crystalline plastics will only melt at high temperatures.

Crystalline Vs. Amorphous Plastics? / /

There are distinct differences between crystalline and amorphous plastics. Crystalline polymers have high density, whereas amorphous plastics have low density. Unlike crystalline plastics, amorphous plastics have poor chemical resistance. Crystalline polymers are translucent or opaque and amorphous plastics are transparent. Amorphous plastics are softer than crystalline polymers and are waterproof.

Crystalline Plastics Injection Molding Finishes / /

Following injection molding, the crystalline plastic part transitions to finishing. During finishing, the part’s appearance or physical properties may be enhanced. Fathom offers the following finishes.

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

Crystalline Plastics Injection Molding FAQs / /

Q: Does Fathom offer injection molding?

A: Yes, Fathom offers injection molding services.

Q: What is injection molding?

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

Q: Is Fathom ISO certified?

A: Fathom’s certifications include ISO 9001:2015, ISO 9001:2015 Design, and ISO 13485:2016. For site-specific certifications, please visit https://fathommfg.com/fathom-manufacturing-certifications.

Q: Is Fathom ITAR certified?

A: Yes, Fathom is ITAR certified. For site-specific certifications, please visit https://fathommfg.com/fathom-manufacturing-certifications.

Q: Is Fathom AS9100:2016 certified?

A: Yes, Fathom is AS9100:2016. For site-specific certifications, please visit https://fathommfg.com/fathom-manufacturing-certifications.

Q: Is Fathom NIST 800-171 certified?

A: Yes, Fathom’s certifications include NIST 800-171. For site-specific certifications, please visit https://fathommfg.com/fathom-manufacturing-certifications.

Q: What is crystalline plastic?

A: Crystalline plastic is a category of polymers with a high melt temperature, excellent strength and stiffness, and better chemical resistance properties.

Q: How does crystallinity affect injection molding?

A: To manufacture crystalline plastics, a substantial amount of energy must be used to bring the material to the proper melting point and melt the material uniformly.

Q: What are crystalline and amorphous plastics?

A: Crystalline and amorphous plastics are both polymers. Crystalline polymers have a specific structure, whereas amorphous plastics have no arrangement or pattern. The lack of pattern causes amorphous polymers’ lower density and chemical resistance.

Q: Is PS crystalline or amorphous?

A: PS or polystyrene is an amorphous thermoplastic.
