At Keyflex, we recognise that every project is unique and requires a tailored plastic injection moulding solution. Our services are designed to deliver flexibility, precision, and reliability, whether you need custom one‑off prototypes or high‑volume production runs. With advanced moulding technology and expert engineering support, we help clients bring innovative ideas to life with confidence.

Thermoplastic Materials & Over‑Moulding
  • Keyflex manufactures precision parts and tooling using a wide range of thermoplastic materials, including:
  • Polycarbonate (PC) – impact resistance and clarity
  • ABS – toughness and dimensional stability
  • Polyester and blends – chemical resistance and durability

Our team provides expert guidance on material selection to ensure optimal performance for your application. We also offer TPR over‑moulding, which delivers a rubber‑like feel, enhanced impact resistance, and improved ergonomics.

 Colour & Finish Options
  • All injection moulded components can be produced in a wide range of colour options, including:
  • Pantone‑matched colours for brand consistency
  • Silver‑plating for a chrome‑like finish
  • Custom textures and surface treatments
Design & File Compatibility

Our plastic moulding design services support multiple 3D file formats, including IGES, STEP, and PARASOLID. We can also design parts in‑house to suit your requirements. By producing both keypads and plastic housings in the same facility, we ensure perfect fit and compatibility, eliminating costly misalignments and guaranteeing smooth operation in the finished product.

Critical Design Considerations
  • To achieve high‑quality injection moulded parts, Keyflex engineers carefully evaluate:
  • Draft Angle – ensuring easy part release from the mould
  1. Undercuts – managing complex geometries without defects
  2. Wall Thickness – avoiding warping or sink marks from uneven thickness
  3. Sharp Steel Edges – reducing stress concentrations and tool wear
  4. Shut‑off Areas & Texture Draft Angles – maintaining precision in textured surfaces
  5. Shrinkage Rates – compensating for material behaviour during cooling
