Plastic Injection Molding

Go from concept to market-ready product with an end-to-end manufacturer

Plastic injection molding is one area of expertise you can leverage when you work with Genimex. We take the Design for Manufacturing (DFM) approach, reviewing and optimizing your designs before tooling begins to reduce costs, accelerate production, and enable scaling. Injection molding supports a wide range of thermoplastics and mixed materials across consumer product categories. Injection molding supports a wide range of thermoplastics and mixed materials across consumer product categories.

What is plastic injection molding?

Plastic injection molding is a manufacturing process in which molten plastic is injected under high pressure into a precision-engineered mold cavity. Once cooled and solidified, the mold opens and ejects the finished part. The process is repeatable, making it ideal for producing large volumes. Injection molding works across a broad range of thermoplastics and thermosetting plastics.

Plastic injection-molded capabilities and processes

Genimex delivers precision injection molding across a wide range of materials and product types. Our capabilities include:

ABS injection molding

Acrylonitrile butadiene styrene (ABS) is valued for its excellent impact resistance, strength, and aesthetic qualities. It is ideal for consumer electronics, automotive parts, and household appliances that require a durable, visually appealing finish.

PP glass fiber molding

Polypropylene (PP) with glass fiber reinforcement offers enhanced stiffness, strength, and dimensional stability. This material is ideal for structural components and applications that demand higher performance and resistance to heat and chemicals.

Blow injection molding

Combines injection and blow molding to produce hollow, seamless parts with precise necks and a polished finish. It is ideal for pharmaceutical bottles, cosmetic packaging, and small beverage containers requiring tight tolerances and high clarity.

Rotational molding

Rotational molding uses a heated, biaxially rotating mold to form large, hollow, stress-free parts with uniform wall thickness. It is ideal for storage tanks, kayaks, playground equipment, and other products with complex geometries that require toughness and durability.

Silicone injection molding

Silicone injection molding uses liquid silicone rubber (LSR) and a catalyst for high-precision, flash-free parts with fast cycle times and excellent repeatability. This process is ideal for medical devices, automotive seals, infant products, and electronic housings that require precision and flexibility.

Plastics that we offer manufacturing support for include, but aren’t limited to:

• Polycarbonate (PC): For transparency, impact resistance, and high heat deflection
• Nylon (PA): For strength, wear resistance, and chemical resistance
• HDPE (High-Density Polyethylene): For flexibility, chemical resistance, and cost-effectiveness
• TPE (Thermoplastic Elastomer): For soft touch flexibility and sealing properties
• Acrylic (PMMA): For optical clarity and weather resistance

We also work with numerous metals, woods, and textiles for mixed-material manufacturing, ensuring the best fit for functionality and performance.

Ensuring quality throughout plastic injection molding

Quality is built into every stage of the Genimex process, from design review and prototype testing through to factory audits and continuous on-site checks at scale. Every injection-molded component we produce is held to the same exacting standards, regardless of volume.
