The best injection molding starts with high-quality raw materials, and AN-Prototype’s plastic injection molding process can be adapted to a variety of plastics, including all thermoplastics and some thermosets as well as liquid silicones. After we understand the basics of materials such as common grades, brands, advantages and disadvantages, we select the appropriate injection molding material according to your application requirements.
ABS
As a high-strength general-purpose engineering plastic, ABS (acrylonitrile butadiene styrene) plastic is a thermoplastic used to manufacture many commercial products for its excellent performance and low price.
Nylon (PA 6)
Nylon PA 6 is a synthetic thermoplastic polymer that offers increased mechanical strength, stiffness, good thermal stability and/or chemical resistance and is very versatile.
POM
POM (polyoxymethylene) is a common engineering plastic. It is very hard, has good wear and moisture resistance, high wear resistance, low friction and dimensional stability.
PC
PC (Polycarbonate) is a naturally transparent or colored lightweight glass-like plastic. It is lightweight, very strong and elastic, and has impact resistance, excellent feature details, and is widely used in many industries, such as lenses, electronic equipment, etc.
Polyamide 6/6
PA 6/6 (Polyamide 6/6, Nylon 6/6) Plastic material with increased mechanical strength, rigidity, good thermal stability and/or chemical resistance.
PVC
PVC (polyvinyl chloride or Vinyl) is a high-strength rigid thermoplastic material and one of the third most widely used synthetic plastic polymers in the world, commonly found in pipes, non-food packaging and decoration.
PP
PP (Polypropylene) is the second most widely used plastic in injection molded parts. It has tough yet flexible properties, can carry light loads at different temperatures for a long time, and is often required to make parts that require chemical or corrosion resistance.
PU
PU (PUR or Polyurethane) is an elastomeric plastic consisting of units of an organic compound combined with urethane (polyurethane). It has high load-bearing capacity, abrasion and impact resistance, tear resistance, and also has water resistance, oil resistance, grease resistance, electrical properties.
Acrylic (PMMA)
Acrylic plastic, also known as plexiglass, is one of the most transparent plastic materials. Due to its low price, high transparency and light weight, it is an ideal replacement for glass in many applications, has good wear resistance, and is ideal for parts or products that work outdoors.
PC-ABS
PC-ABS (Polycarbonate-ABS) is the optimal combination of PC and ABS, a high impact thermoplastic with higher strength engineering thermoplastics. It combines the strength and heat resistance of PC with the flexibility of ABS, which is slightly more flexible than standard polycarbonate.
Polyethylene (PE)
PE (polyethylene) is a lightweight, durable thermoplastic with high ductility, abrasion and chemical resistance, commonly used in packaging, pipes, films, bottles and more. PE is one of the most commonly used plastics in the world.
HDPE
HDPE (High Density Polyethylene) has an excellent strength-to-weight ratio and chemical resistance. It is a thermoplastic polymer produced from the monomer ethylene and is widely used in fuel tanks, connector insulators, food containers and outdoor products.
PC-PBT
PC-PBT is a tough and rigid plastic material that is resistant to lubricants, solvents and cleaning agents and is often used in electronic housings.
PEEK
PEEK (polyether ether ketone) is an organic thermoplastic polymer, an engineering plastic with excellent chemical resistance, excellent abrasion resistance, and moisture resistance. It has superior tensile strength that surpasses most plastics and is often used as a replacement for metal parts in high temperature, high stress applications.
LDPE
LCP (Liquid Crystal Polymers) have mechanical properties as well as low dielectric constants even at high temperatures. This material offers excellent functionality for micromolding and thin-walled parts. LCPs are widely used in electrical connectors and interconnects as well as medical equipment.

Custom Injection Molded Parts Finishes
SPI is a standard developed by the American Plastics Industry Association for the plastics industry to identify the appearance quality of plastic parts. AN-Prototype also uses the SPI standard to define the finish of plastic injection molded parts. SPI’s standard specifies 12 finish grades, grouped into four categories ranging from shiny to dull. Each grade has a different requirement for perfect allowable deviation, the lower the number, the smaller the deviation, and the higher the number, the greater the deviation.
Standard Finish
Depending on the specific geometry and draft depth of the part design, the finish chosen by the moldmaker is typically SPI B-2,semi-polished finish..
Glossy
If your plastic parts require the smoothest surface possible, SPI grades A1, A2 and A3 are recommended. The manufacture of molds of this grade requires hardened tool steel with diamond-polished surfaces. Mirror gloss provides an almost mirror-like smooth finish.
Semi-glossy
If your plastic part requires a semi-gloss finish, AN-Prototype recommends SPI grades B1, B2 and B3. Sanding molds to create parts with a semi-gloss finish is ideal for removing tooling and mold marks.
Matte
If you need plastic products that require a matt finish, then we recommend SPI grades C1, C2, C3. Usually sand-polished molds are used for making parts with a matte finish.
Textured
If the plastic part requires a textured surface, AN-Prototype recommends the use of SPI grades D1, D2 and D3.
Threaded Inserts
We can install most commonly used standard inserts in UNF and metric sizes.
Pad Printing
Transfer a 2D image onto a 3D part. All images are subject to review.
Laser Engraving
Engrave part numbers, logos, and more onto your parts.
Additional Finishing Options
After processing, injection molded parts can be further finished or coated, which can change the appearance, surface roughness, hardness and chemical resistance of the produced parts.
