Prototypes Injection Molding Tolerance

Name	Tolerance Range
Standard Prototypes	+/- 0.2 mm to +/- 0.5 mm
High-Precision Prototypes	+/- 0.05 mm to +/- 0.2 mm
Complex Prototypes	+/- 0.2 mm to +/- 0.5 mm

Prototypes Injection Molding Materials

PP

PP (Polypropylene) is chemical-resistant, flexible, and cheap, the ideal material for most types of use in packaging, automotive parts, and household items. For instance, PP is common in food packets, bottle caps, and bumpers of cars because it’s hard and resistant.

Mill Lead Time: Up to 5 days
Color: Natural, white

PETG

PETG (Polyethylene Terephthalate Glycol) is chemical resistant, rigid, and transparent and is ideal for functional prototypes and end-use products. PETG is applied widely in medical devices, food packaging, and showcase cases. PETG, for example, is normally applied for medical device enclosures due to its rigidity and transparency.

Mill Lead Time: Up to 4 days
Color: Clear, black, white

PLA

PLA (Polylactic Acid) is biodegradable plastic and is used in prototyping and low-stress applications. It has low molding temperature and gives a smooth finish surface. It is suitable for disposable packaging, consumer items, and educational prototypes. For instance, PLA is used extensively in food packets and 3D-printed prototypes.

Mill Lead Time: Up to 2 days
Color: White, translucent

ABS

ABS (Acrylonitrile-Butadiene-Styrene) is one of the injection molding materials of choice due to the fact that it possesses adequate mechanical strength, impact strength, and processibility. It is applied in a wide variety of products ranging from automotive trim, electronic enclosures, and household items to car dashboards and toy parts, for example. The reason being its hardness and finish.

Mill Lead Time: Up to 3 days
Color: Black, neutral matte finish

PC

PC (Polycarbonate) is incredibly strong, clear polymer with great impact-resistance and consequently applied in protective gear, lenses, and electronics. For instance, PC is largely applied in protecting eyeglasses, phone covers, and automobile headlights due to its hardness and transparency.

Mill Lead Time: Up to 6 days
Color: Clear, black

PA

Nylon (Polyamide) is equally wear-resistant, hard, and elastic and thus utilized in gears, bearings, and structure components. Nylon is commonly used in the industrial and vehicle industry. Nylon, for example, will normally be used in gears as well as in sliding components printed using 3D printing since it is of low friction and high resistance.

Mill Lead Time: Up to 5 days
Color: Natural, black

POM

POM (Polyoxymethylene) is a hard, low-friction plastic well adapted for precision parts such as bearings, gears, and fasteners. POM is extremely commonly used in mechanical engineering, not to mention the automotive industry. POM, for example, is extremely commonly used in 3D-printed gears due to wear and dimensional stability.

Mill Lead Time: Up to 4 days
Color: White, black

PEEK

PEEK (Polyether Ether Ketone) is a high-performance thermoplastic with superior mechanical properties, chemical resistance, and thermal stability. PEEK is employed in aerospace, medical implants, and industrial parts. For example, PEEK is applied in 3D-printed aerospace components due to its thermal and strength stability.

Mill Lead Time: Up to 7 days
Color: Natural, black

PPS

PPS (Polyphenylene Sulfide) is extremely durable, chemical resistant, and heat resistant, thus qualified for application in automobile and electrical use. For instance, PPS has extensive application in 3D-printed fuel system components and electrical connectors.

Mill Lead Time: Up to 7 days
Color: Natural, black

PVDF

PVDF material (chemical designation Polyvinylidene fluoride) is processed by Ensinger into standard product form as sheets and rods. Polyvinylidene fluoride is a semi-crystalline, opaque, thermoplastic fluoropolymer. PVDF is exceptionally adept at chemical resistance without low mechanical values and/or processing problems that are typically characteristic of other fluoropolymer materials. 171 degrees Celsius is the melting point for PVDF material.
