At ALL-IN OPTICS, we provide various services such as the mass production of plastic lenses.
We have highly trained experts with more than 15 years of experience dealing with such high-quality productions.
Different transparent materials are designed for the specific market and application, and these materials play an important part in our day to day lives.
This production is cost-efficient and of high-quality, but before the series is possible, a whole process connection must be completed from lens design to producing the prototype.
The production of transparent material within injection moulding needs to be carried out by special injection moulding machinery. The handling of the product and process of the material needs to be also strictly carried out. There needs to be a high requirement paid to plastic product quality; any hole, marking, whitening or discoloration must be eliminated as it will be visible within a transparent Lens.
During the storage and transportation stage, the material must be sealed and kept clean. If or when drying stages are happening the air used should be filtered to avoid polluting the raw material. The main Materials that are used for producing plastic Lenses are PMMA, PC, COC or COP Material.
Plastic injection moulding is the process of melting plastic granulate that once malleable enough, are injected at pressure into a mould cavity, which fills and solidifies to produce the final product.
Related to the Lens production there might be some special processes which are needed some times – such as Compression Moulding or variothermal heating and cooling.
Hot embossing is a technique to fabricate high-quality microstructures. The technique can be quite a challenge due to the high surface volume ratio. The typical materials used for this are PMMA or Polycarbonate. There need to be significant steps taken within this process.
There are typically four steps of embossing, pre-heating, embossing, demoulding, and cooling. The requirement is good process control at elevated temperatures and is often used for large area polymer devices with micro and nanostructures such as microlenses and anti-reflective polymer films.
Extrusion, similar to our other services, is completed by using a high volume process and is used to manufacture a broad range of products, including linear lenses. The method is created by melting raw plastic pellets and forming melted material into a constant form. Extrusion is a process that involves minimal waste that is recyclable, and our experts can offer this service with efficiency and high quality. Extruded Lenses are most likely used in LED Lighting industry.
