Volumes
Talk to us about your quantity requirements. Minimums are determined by part design, including set-up and material requirements, and maximums are negotiable. We recently produced in excess of 2 million parts for one project.
Mold Making
Our molds are made using the material most appropriate for your needs: aluminum, if speed and economy are your priorities; P20 stainless steel if maximum longevity is your top requirement.
Resins
You can get the right product for the job with our access to industry materials specialists who are experts on the properties and behaviors of hundreds of different materials. Maybe achieving your required strength is as simple as adding a certain filler, you’ll get the answer.
Commonly used resins include:
ABS (Acrylonitrile Butadiene Styrene): Medium strength. Used for light, rigid molded parts like piping or automotive body parts. Ex. LEGO bricks
PC-ABS blends (Acrylonitrile Butadiene Styrene/Polycarbonate): High strength, heat resistance, and rigidity. Used for automotive, electronics, and telecom applications.
LCP (Liquid Crystal Polymer): Excellent in thin applications, high chemical resistance. Common for electrical and mechanical parts, also food storage containers.
PA6 (Nylon): Excellent toughness and wear/chemical resistance. Used for medical, automotive, and industrial components.
PEEK (Polyether ether ketone): Extreme temperature/pressure applications, sterilize in autoclave, FDA-approved for food contact. Used in aerospace, automotive, and medical applications.
Polycarbonate: Holds tight tolerances, variety of colors, transparency with impact resistance. Common in aircraft, electronics, and telecom applications.
Polypropylene (PP): Good moisture resistance, impact strength, low cost. Suitable for automotive, marine, and RV parts.
PolyVinylChloride (PVC): Very dense, rigid, readily available and inexpensive.
Acetal (POM): High wear resistance; good for bearings, gears, and other functioning parts.
Acrylic (PMMA): ideal for applications where a polycarbonate wouldn’t work well such a lenses requiring lasting clarity.
Copolyesters: used in the medical industry because of tolerance to aggressive cleaning products.
