Material Options For Injection Molding


ABS (Acrylonitrile Butadiene Styrene) is a popular thermoplastic widely used in injection molding due to its excellent mechanical properties and versatility.

Renowned for its robustness, high impact resistance, and easy moldability, ABS finds it’s applications ranging from automotive components to consumer electronics.

Products crafted from ABS through injection molding often exhibit superior surface finish, dimensional stability, and resistance to various environmental stressors, making it a favored choice for many manufacturers.


PEEK (Polyether Ether Ketone) is a high-performance thermoplastic esteemed for its remarkable strength, thermal stability, and chemical resistance.

PEEK injection molding part is often chosen for advanced applications in aerospace, medical, and electronics industries, PEEK stands out for its ability to retain its mechanical properties even at elevated temperatures.

Injection molded components made from PEEK are characterized by their long-term durability, low moisture absorption, and exceptional resistance to wear and abrasion, making them an indispensable material for demanding engineering environments.


HDPE (High-Density Polyethylene) is a robust and dense thermoplastic recognized for its high strength-to-density ratio.

Widely used in applications like containers, piping, and geomembranes, HDPE is prized for its resistance to impact, moisture, and chemicals.

Injection-molded products crafted from HDPE are known for their longevity, recyclability, and ability to withstand environmental stressors, such as UV radiation. This combination of features makes HDPE a go-to material for industries aiming for durable and sustainable solutions.


PET (Polyethylene Terephthalate) is a transparent, lightweight thermoplastic that stands out for its impressive strength and gas barrier properties.

PET is Frequently chosen for packaging applications, especially in the beverage industry, PET bottles and containers offer clarity comparable to glass, yet with superior shatter resistance.

Injection-molded products made from PET are characterized by their crystal-clear transparency, recyclability, and resistance to water and most chemicals.



TPE (Thermoplastic Elastomer) is a unique class of materials that combines the characteristics of rubber with the processing capabilities of thermoplastics.

Injection-molded products made from TPE are distinguished by their elasticity, ability to return to their original shape after stretching, and excellent UV and weather resistance. Their adaptability and wide range of hardness levels make TPEs a versatile choice for manufacturers aiming to bridge the gap between plastics and elastomers.

Notably flexible, durable, and recyclable, TPEs are often utilized in applications that require a soft touch, such as grips, seals, and medical devices.

Nylon materials for Injection Molding

Nylon, often referred to by its chemical name, Polyamide (PA), is a versatile thermoplastic lauded for its excellent balance of strength, durability, and thermal resistance.

Injection-molded products crafted from Nylon exhibit superior mechanical properties, good dimensional stability, and resistance to many chemicals and environmental factors. Given its adaptability and intrinsic toughness, Nylon remains a favored choice for manufacturers seeking high-performance solutions in both high and low-temperature environments.

Predominantly utilized in automotive, electronics, and textile industries, Nylon is known for its impressive wear resistance and low coefficient of friction.

Polyethylene, commonly abbreviated as PE, stands as one of the most widely used thermoplastics globally.

From plastic bags to hard containers, Polyethylene’s diverse use stems from its ease of processing, resistance to chemicals, and excellent moisture barrier properties. Injection-molded products made from Polyethylene are characterized by their durability, recyclability, and adaptability to both rigid and flexible formations, making it a staple in countless industries and households alike.

Finishing Options of Injection Mold

Standard Finish

Often being SPI B-2, subject to the design’s geometry and draft angles. The inner surfaces, which aren’t aesthetic-focused, are usually left in their machined condition.

SPI Finishes

Spectrum of finishes based on the Society of Plastics Industry (SPI) standards, spanning from Grade 3 diamond/high gloss to 320 stone subdued polish. The finishes encompass: SPI A-1 through A-3, SPI B-1 through B-3, SPI C-1 through C-3, and SPI D-1 through D-3.
