Design for Manufacturing
We work closely with your team to refine designs for the injection molding process, addressing potential challenges and optimizing for efficient tooling. This approach helps reduce production costs, minimize waste, and ensure your design is ready for seamless mass production, without sacrificing quality or performance.
High-Volume Manufacturing
Our injection molding services handle high-volume production for medical, military, and consumer products. We oversee each stage, from mold design to production, ensuring parts meet your specifications with consistent quality throughout every run.
Moldable Materials
Our injection molding process supports a wide range of moldable materials, including thermoplastics like ABS, nylon, and polycarbonate, as well as elastomers for flexible components. We work with both common and specialty resins, allowing us to meet specific requirements for strength, durability, and temperature resistance. Material selection is guided by the needs of your project, ensuring optimal performance and quality for both prototypes and large-scale production.
ABS
A tough, impact-resistant plastic often used in automotive parts and consumer electronics due to its durability
Polypropylene
A lightweight, chemical-resistant material commonly used in packaging, textiles, and automotive components
Nylon (Polyamide)
Known for its strength, toughness, and wear resistance, often used in mechanical and automotive components
Polystyrene
A rigid, low-cost plastic commonly used in packaging, disposable consumer goods, and insulation products
Polycarbonate
A transparent plastic known for its high impact strength and heat resistance, used in medical devices and eyewear
TPE/TPU
Flexible, rubber-like materials ideal for seals, gaskets, and soft-touch parts with elasticity
About our Molding Process
How it Works
Design Optimization: Collaborate to finalize the design and select appropriate materials.
Tooling: We create custom molds using advanced CNC machining for precision.
Injection Molding: The parts are produced in 20-40 second cycles
Quality Assurance: Dimensional accuracy checks, surface finish evaluations, material certification
What's Needed?
CAD files or 3D models of the part design and specifications for material, tolerances, and production volume.
