Enquiry-to-Production Process

Konsa provides practical manufacturing input during development but is not positioned as a standalone industrial design consultancy.

  1. Step 1

    Enquiry and Drawing Review

    Review drawings, samples or specifications to understand the component, material and production intent.

  2. Step 2

    Tooling Assessment or Design

    Assess existing tooling or plan new mould manufacture through the in-house toolroom.

  3. Step 3

    Mould Manufacture or Preparation

    Manufacture new tooling or prepare and verify existing moulds for trial production.

  4. Step 4

    Trial and First-Off Approval

    Run trial shots and first-off samples for customer review before repeat production.

  5. Step 5

    Production Moulding

    Repeat injection moulding once tooling and samples are approved for production.

  6. Step 6

    Optional Assembly and Support

    Discuss any additional finishing or assembly requirements relevant to the project.

In-House Toolroom Advantage

New mould manufacture, repairs and modifications are supported through Konsa's toolroom and Engineering & Tooling division.

  • Single Accountable Supplier

    Tooling and moulding managed at one facility, reducing handover between external toolmakers and moulders.

  • Faster Communication

    Direct communication between toolroom and moulding teams when tooling changes or production issues arise.

  • Easier Repairs and Modifications

    Mould repairs and modifications can be actioned in-house without sending tools off-site.

  • Reduced Transport and Coordination

    Less movement of tooling between suppliers, simplifying project management for customers.

Related support: in-house tool and die manufacturing, reverse engineering of legacy components, and electronics manufacturing for enclosure coordination.

Materials Commonly Moulded

Final suitability depends on material grade, part geometry, wall thickness and tooling design.

  • Polypropylene (PP)
  • Polycarbonate (PC)
  • Selected flame-retardant thermoplastic grades
  • Other materials assessed according to grade, tooling and processing requirements

Typical Applications

These examples illustrate common requirements and do not define the full range of work Konsa can assess.
