Hofmann – Ihr Impulsgeber / Increasing efficiency

Increasing efficiencyin toolmaking

Maximise your production output and reduce costs with our comprehensive optimisation options. We optimise your production processes even before your mould is manufactured – ensuring maximum product quality and the fastest cycle times.

Your benefits

Tailor-made optimisation of your injection moulding tools by us means for you

Cost savings: Reduced material and energy costs through optimised processes.
Higher production output: Shorter cycle times and improved machine uptime.
Highest quality: Accurately manufactured moulds and parts with minimal tolerances.
Faster time-to-market: Reduced development and production times through the use of the latest simulation and manufacturing technologies.

Cycle time optimsation

The cycle time of a mould can be influenced by many factors. For example, the use of faster crystallising resins can significantly reduce the overall cycle time. Effective cooling of the mould is also crucial, as is the optimum setting of injection speed, pressure and holding pressure.

In order to find the right solution for you, we may also liaise with material and injection moulding machine manufacturers. This will ensure maximum efficiency of your mould by adjusting the following aspects:

- Tool design
- Product design
- Cooling strategies
- Heating strategies
- Material selction
- Machine parameters
- Automation

Design optimisation

Mould design

Mould design has a significant impact on the quality and efficiency of the injection moulding process. Our experts design precise moulds that ensure uniform material distribution and minimise rework. This is achieved, for example, by

Optimised sprue and runner designs: Ensuring consistent material distribution and minimising material loss.
Use of simulation tools: Avoiding dead zones and ensuring uniform cooling.

Product design

Efficient product design is the key to successful production. Through targeted design adaptation, we ensure that your product is easier and more cost-effective to manufacture, without compromising its functionality. We achieve this through

Geometric adjustments: Optimising wall thicknesses and rib structures to save material and increase strength.
Demoulding chamfers: Implementing appropriate demoulding chamfers to facilitate the demoulding process and reduce cycle time.

Cooling strategies

You can rely on our bespoke cooling systems to ensure uniform and rapid cooling of plastic parts.
This includes

Close contour cooling channels: Optimising the cooling channels according to the mould contour to improve cooling performance through additively manufactured cooling channels.
Use of high performance materials: Using materials such as copper alloys for efficient heat dissipation.

Heating strategies

Optimised heating strategies are essential when processing temperature sensitive materials.
We ensure that your mould is heated quickly and evenly to the required temperature:

Induction heating: Fast and uniform heating of the mould.
Temperature control units: Precise control of mould temperature for optimum processing. We use temperature control units from Regloplas, Single and Technotrans, among others.

Material selection

Choosing the right material is critical to the longevity and quality of your end product. We source a variety of materials to suit your specific requirements. These include

Standard and high performance steels

FASTCOOL® 50: Steel with very high thermal conductivity, also ideal for glass fibre reinforced parts.
1.2312: Highly machinable steel, ideal for mould plates and fittings.
1.2738: Easily machinable steel, uniform hardness even in thicker plates.
1.2343: Hot work tool steel, ideal for high gloss polishing and mould inserts.

High conductivity coppler alloys

Ampcoloy: Quickly and reliably reduces temperatures in critical areas of the tool.

Filling Simulation Software for Mould Optimisation

Mouldflow analysis

Our Moldflow analysis allows us to identify and eliminate potential problems such as shrinkage and warpage before the mould is even built. This helps to reduce development times and improve product quality. For you, this means maximum efficiency, saving you not only time but also money.

Applications for filling simulation

Cascade simulations
MuCell calculations
Injection moulding calculations
Warpage analysis
Mould temperature control optimisation
