Injection Molding Capabilities

From mold design and tooling to insert molding, overmolding, and precision production, we support plastic parts from prototype validation through mass production. Material selection, mold-flow analysis, and Design for Manufacturability (DFM) review help reduce tooling risk and improve repeatability.

Injection Molding Materials

Choose from ABS, nylon, PBT, PC, PE, PP, PVC, acrylic, acetal, TPU, PEEK, and other engineering plastics or elastomers. Each material offers different trade-offs in strength, heat and chemical resistance, wear, transparency, insulation, and cost.

Our engineers can recommend a resin and grade based on load, appearance, operating environment, compliance needs, and budget, then tune the molding process for stable production.

PA (injection molding)
PBT (injection molding)
Polycarbonate (PC)
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl Chloride (PVC)
Acrylic (PMMA)
Acetal (POM)

Why Choose XFabro for Injection Molding

Get drawing analysis, DFM feedback, process-matched quoting, engineering review, and quality control from tooling through production.

  1. Automated 2D/3D File Analysis

    We analyze STEP, IGES, STL, DWG, and DXF files for geometry, wall thickness, ribs, undercuts, holes, inserts, and assembly features to support tooling review and quoting.

  2. Design for Manufacturability (DFM) Review

    Engineers review wall thickness, draft angles, ribs, undercuts, parting lines, gates, venting, shrinkage, and warpage risks, then recommend practical design changes before tooling.

  3. Process-Matched Quoting

    Quotes account for geometry, resin, size, quantity, finish, tooling type, cavity count, and molding process so you can compare practical price and lead-time options.

  4. Engineering Review and Quality Control

    Engineers verify the molding process and key parameters before production. In-process inspection checks dimensions, structural performance, and surface requirements against the approved design.

  5. Engineering Plastics and Tolerance Control

    Select from ABS, PC, PA, PP, POM, TPU, TPE, PEEK, and other resins. We clarify achievable dimensional and appearance controls for the selected material, geometry, and process.
