TOOLING

Tooling

By designing and manufacturing all tools ourselves, we gain control over the entire process from order to delivery.
Regardless of whether a single prototype tool is involved or a series production tools.

Inhouse manufacturing brings speed and control

Peace of mind and quality throughout the entire manufacturing process are our hallmark. Before manufacture, we simulate the injection moulding so that we can detect any defects and risks with the fabrication at an early stage. We then fabricate the tool and you receive the resulting samples and reports. 

Reliability brings peace of mind.

The tool is fine-tuned

The tool can be customised for various type of input, e.g. edge, bar, submarine, tunnel, film or hot gate. The tool’s surfaces can be e.g. blastered, polished, grinded, spark eroded or etched to obtain the desired surface texture on the injection-moulded parts. The tools are fitted by our own staff. Before injection moulding, we pressure test the tool to ensure it is correct.

The work process before the production of parts starts

1

Analysis

In order to quality-assure our process, we always simulate the injection moulding. This allows us to identify early on any problems and risks with the fabrication. Any adjustments are made, followed by new simulations. As a result, we can reduce the number of adjustments and offer a more cost-effective product.

2

Design

Our own tool designers fabricate the tool. Depending on the type of tool, the construction is customised to obtain manufacture that is as cost-effective as possible.

3

Milling

The tool is milled by our own staff in our CNC workshop. Automated preparation and pick robots which supply milling machines with items mean efficient manufacture.

4

Assembly

The tool is assembled by our own staff in our die workshop. This is also where the sanded, ground or polished surfaces are created that will give the end product its surface finish. Before injection moulding, we pressure test the tool to ensure it is correct.

5

Verification

The tool is test injected to obtain samples. Verification of the injection parameters and checks with the customer’s requirements specification to ensure the requirements are met. Documentation, e.g. measurement reports and PPAP, by arrangement with the customer.

We offer the correct technology in each case

Prototype tool

Construction of the tool is simplified as much as possible to meet the number of parts that are to be manufactured. The tool is made from aluminium, resulting in rapid and efficient manufacture and allowing investment costs to be kept as low as possible. Parts can be injection-moulded in the tool under production-appropriate conditions. Usually a few hundred parts are made.

Low-volume tools – aluminium

Construction of the tool is adapted for a more automated injection moulding process. The tool is made from aluminium, resulting in rapid and efficient manufacture and allowing investment costs to be kept as low as possible. Parts can be injection-moulded in the tools under production-appropriate conditions. The life time of the tool is up to 100,000 cycles, which covers the service life of a huge number of parts.

High-volume tools – steel

The tool is made from steel and is often procured from Asia. Our own staff check the time schedules on site, are present at test runs, take care of the delivery of sample parts as well as shipment of the mould tool to Sweden. Seamless handling on start-up is assured, since all manufacturing is performed according to our tool standard that has been produced.

Guidelines

  • The choice of material affects the shrinkage allowance required from the tool.
  • The choice of material can affect the service life of the tool.
  • If we are involved early on the project, we can help you by providing critical product assessments to ensure the part is better suited for quality-assured manufacture.
  • The quantity of parts to be manufactured will impact on the tool solution. Are they prototypes, low-volume series or high-volume runs?
  • Number of cavities? More cavities will increase the tool costs, but reduce the parts cost.
  • The tool is more complex if the part is highly ribbed.
  • The tool is more complex if the die needs to be opened and closed.
  • Are cast-in parts required?
  • What kind of surfaces should the tool have? Milled, blastered, grinded, spark eroded, etched?
  • Can there be a visible inlet?
