Design and in-house toolmaking

Custom mold manufacturing

We manufacture molds for plastic injection molding, compression molding, MIM and aluminum casting. Each design is tailored to your part, material and production volume — from the technical brief to the finished tool.

Molds for your production requirements

We choose the design to suit the process, part geometry and requirements for the finished component.

Design and manufacturing capabilities

The cavity count, runner system and mold mechanisms are selected for each project and the equipment on which the tool will operate.

Our own toolmaking facility

We manufacture components, assemble molds and carry out fitting and adjustment in-house. Parts and assemblies are checked against the design documentation.

From 3D model to finished mold

Molds designed by our engineering bureau and manufactured in our own toolroom.

A four-cavity mold for a thin-walled ABS part.

  • Four parts per cycle

    The multi-cavity design increases output without lengthening the molding cycle.

  • Precise forming inserts

    The thin labyrinth ribs call for precisely made inserts, produced with EDM, grinding and finishing.

  • Tested before handover

    The mold is tested on our own injection molding equipment and the trial parts are inspected.

From the technical brief to the finished mold

We agree on the technical decisions step by step and check the results throughout manufacturing.

  1. Reviewing the brief

    We review drawings, a 3D model or a technical brief: geometry, material, part requirements and planned production volume.

  2. Design

    The mold is designed for the customer’s process and equipment. Where needed, we recommend changes to improve part manufacturability.

  3. Design approval

    We agree on the design and technical requirements. Manufacturing begins once the documentation is approved.

  4. Manufacturing and assembly

    We machine the components using mechanical and EDM processes, inspect the parts, then assemble and adjust the mold.

  5. Trials

    We check mold operation and sample parts against the agreed requirements under an agreed trial plan. We provide trial samples to the customer for approval. Trial arrangements are defined for each project.

  6. Adjustment and delivery

    We make any adjustments required after trials. The finished tool is delivered, or part production is arranged under the terms of the order.

Materials and components

We use tool steels and components from specialist manufacturers, including Böhler, DME, Pro Plastica, Mold-Masters and INCOE. Materials for forming components, guides, ejection assemblies and runner systems are selected to meet the project requirements.

Manufacturing and quality under control

Designers, manufacturing departments and inspection teams work within a single production process.

Trials at our own production facility

We test molds for plastic injection molding, compression molding and MIM in-house. We check the mechanisms and the quality of sample parts, using the results to adjust the tooling.

  • Design and manufacturing together

    Design decisions are coordinated with manufacturing, from the documentation to assembly of the finished mold.

  • Inspection of parts and assemblies

    Manufactured components are checked against the documentation at the relevant stages of the production process.

  • ISO 9001:2015 quality management system

    Our company operates a quality management system certified by TÜV Thüringen to ISO 9001:2015.

Before you order

What do you need to prepare a quotation?

Send drawings, a 3D model or a technical brief. Include the part material, requirements and planned production volume. We can work with you to clarify any missing information.

Which molds do you test in-house?

We carry out in-house trials for plastic injection molds, compression molds and MIM molds. The trial plan and conditions are agreed according to the design and process for each project.

How long does manufacturing take?

Lead time is determined after reviewing the technical brief. It depends on design complexity, materials, components and the scope of work, and is agreed for each order.

How do you select materials and components?

Tool steels, guides, ejection assemblies and runner system components are selected according to the part material, operating conditions and project requirements. We use products from specialist manufacturers.

What warranty do you provide for molds?

We provide a warranty on the molds we manufacture. The warranty terms are specified in the mold’s technical passport: 12 months or a specified number of operating cycles, depending on the mold type.

Can a mold be repaired or modified?

We repair and modify tooling. Feasibility and the scope of work are determined after reviewing the mold’s condition and the available design documentation.
