Production control system

Quality Control

Mold quality is ensured not by a single check at the end of the project, but by control at every stage of production.

The customer is provided with the following documents:

  • Mold Base Inspection Report;
  • Steel Material Inspection Report;
  • IQC Report;
  • IPQC Report;
  • Sample Inspection Report.

01 / Quality management

Management system and control records

The quality management system includes ISO 9001 and ISO 13485. Production control covers IQC, IPQC, mold base inspection, steel inspection, sample inspection and final inspection before shipment.

Product quality starts at the design stage: for complex parts, an agreed Moldflow analysis or an equivalent CAE simulation helps reduce the risk of warpage, sink marks, air traps and unwanted weld lines in advance.

ISO 9001:2015

The ISO 9001 certificate and its current scope are provided during approval.

ISO 13485

The ISO 13485 certificate and its current scope are provided during approval.

Stage-by-stage control

Incoming and in-process inspection, mold trials and sample checks are performed according to the project quality plan. Acceptance criteria are agreed with the customer.

02 / IQC

Incoming inspection

IQC, steel inspection and mold base inspection are performed before materials and components are released to production.

Steel
Steel inspection is documented in a report; the characteristics checked are defined by project requirements.
Mold base
Mold base inspection is documented in a report according to the agreed control plan.
IQC
IQC results are recorded in control records; sampling and acceptance criteria are defined by the project quality plan.

03 / IPQC

In-process inspection

IPQC accompanies CNC, EDM, wire EDM, assembly and the first trial. Tolerances, measurement frequency and control points are set by the project quality plan.

01

CNC

In-process inspection belongs to the manufacturing stage. The measurement plan after CNC is defined by the component’s geometry and tolerances.

02

EDM

After EDM, machined surfaces and dimensions are inspected according to the project plan.

03

Wire EDM

Wire EDM is a separate stage. The profile verification method is chosen based on geometry and drawing requirements.

04

Assembly

After approval and machining, the flow includes assembly, first trial and, if necessary, design and mold corrections.

Tolerances and control points are agreed in the project’s technical documentation.

04 / Measuring equipment

Measuring and inspection equipment

Measurement ranges, required accuracy and the inspection method are defined by the requirements of the specific part.

Measurement ranges, required accuracy and inspection conditions are defined for the specific task. Documentation for the measuring equipment is provided during approval.

05 / Mold trial

T1, sample inspection and corrections

The production process includes a first trial after assembly. Based on the result, the mold either moves forward or returns for design changes, rework, assembly and another trial.

  1. 01Mold assembly

    Follows design approval and component manufacturing.

  2. 02First trial / T1

    The mold is tried out after assembly. In-house machines cover the 90–530T range.

  3. 03Sample inspection

    Sample inspection results are documented in a report.

  4. 04Corrections

    The process allows for design changes and repeated production if necessary.

  5. 05Confirmation

    After the repeated cycle, the trial and handover/shipment take place.

06 / Before shipment

Final inspection

Before shipment, sample inspection, final inspection and mold acceptance are performed after trials and any necessary corrections.

Dimensions
Dimensional inspection is performed with measuring equipment; the content of the measurement report is defined by the control plan.
Mold function
After corrections, the mold undergoes another trial.
Visual inspection
Visual inspection is performed before final acceptance and packaging.
Packaging
Packaging requirements and their verification are agreed for each delivery.
