Injection moulding of transparent plastics

Crystal-clear production: flawless products

Every year, we process hundreds of tonnes of transparent plastics such as polycarbonate and PMMA. We use these to manufacture a wide range of products, from optical components for the lighting industry to parts for household goods.

To produce flawless, transparent products, high-quality moulds are required, with all shaping surfaces polished to a high gloss. This polishing is a true craft and is generally carried out entirely by hand by our experienced mould makers.

Special-purpose machinery

When dark-coloured plastics are processed on machinery, residues often remain in the sharp corners of the machine. If transparent materials such as PC or PMMA are then processed at relatively high material temperatures, these residues may break away into very small pieces, causing contamination with particles or streaks in the product.

To ensure that no contamination occurs in transparent products, we have a large production facility equipped with machinery that processes only transparent materials. Here, we work in a clean, dust-free environment to achieve a perfect result.

Specialist knowledge

Polycarbonate and PMMA are materials that are difficult to process and require specialist knowledge of processes and parameters. Particularly when dealing with complex shapes – such as those with significant variations in thickness, like lenses – it is the years of experience of our skilled professionals that make all the difference.

Highest precision, no visible flow lines and the ability to remove the product from the mould without scratching it: these are examples of the challenges involved in manufacturing transparent components, where experience can make all the difference.

Special moulds

To produce beautifully transparent products, a mould must be polished to a high gloss. This is a traditional craft in which De Beer Plastics boasts decades of combined experience. However, it is not just the surface finish that requires specialist expertise; the entire mould construction, including ejection and cooling, demands a different approach to that used for standard plastics.

The polished surface also makes the moulds vulnerable, as even the slightest scratch will be visible in your product. That is why we place great importance on our in-house mould-making departments. This ensures that full responsibility remains with a single party, and should any unexpected issues arise, we can respond immediately and carry out professional repairs.
