Mold Materials

We provide customers with exceptional plastic injection molding. Utilizing an exhaustive selection of thermoplastic materials, we take pride in knowing our customers have more options to choose from for their plastic parts. We use only thermoplastic materials that we feel are capable of surpassing both ours and our customers' expectations in terms of quality and performance.

Our supervised manufacturing cycle helps to ensure that your injection-molded plastic parts and components are made with nothing but the utmost precision. Additionally, we reinforce that our plastic parts are of the highest quality by adhering to all ISO-9000 requirements.

Properties to Consider When Selecting Thermoplastic Material

  • Electrical and Optical: Dielectric constancy and strength, electrical resistance
  • Mechanical: Tensile strength and elongation, impact loading, fatigue endurance
  • Physical: Tensile yield strength and tensile modulus
  • Processing: Water absorption, viscosity, and melt flow index (MFI)
  • Thermal: Thermal conductivity, transition temperature

Thermoplastic Materials We Use

  • ABS: Also known as acrylonitrile butadiene styrene, this material is ideal for lightweight yet rigid injection-molded parts
  • Acetal (Delrin® from DuPont™, Celcon® from Celanese AG Ticona)
  • Acrylic: With similar properties as glass, this material is extremely durable
  • Nylon-PA (Zytel® from DuPont™): Ideal for products that function in extreme temperatures, near toxic chemicals, or at high humidity levels
  • PBT (Valox®): Also known as polybutylene terephthalate, this material offers both high and low temperature performance
  • PET (Rynite® from DuPont™): Not only durable, but also lightweight and performs well throughout various temperatures
  • Polycarbonate (Lexan® from General Electric): Tends to be more expensive but only due to its outstanding physical properties
  • Polyetherimide (Ultem® from General Electric): Long-term, durable and capable of withstanding high temperatures
  • Polyethylene: Considered a more commonly used thermoplastic
  • Polyphenylene Sulfide-PPS (Fortron® from Celanese AG Ticona, Ryton® from Chevron Philips Chemical): Reinforced with either glass or fillers, this material provides durable strength for your plastic parts
  • Polypropylene: This material is both stress and crack-resistant
  • Polystyrene: Great chemical, stress, and weathering resistance
  • Thermoplastic Elastomers (Santoprene® by Advanced Elastomer Systems (AES), Kraton® by Kraton Polymers): Resistant to weathering, solvents and abrasion, and ideal for processing
