ToolshopMold Making for Precision Optical parts

Clever concepts precise implementation

The basis of every injection-molded precision optic is the right mold concept and high-precision mold construction. This is because the mold directly determines the product quality. In order to achieve reliable repeatability, tolerances in the micrometer range and optimum component performance during injection molding, molds designed for plastics and optics are required.

With our experience in article and tool design, coupled with craftsmanship and high-tech, we create customised solutions with added value. As a partner to the automotive industry, medical technology and sensor technology, we know the material and mould requirements of complex optical applications inside out.

Mold Design for Precision Injection Molding

Mold Design for Precision Injection Molding

The design of high-precision injection molded parts and the associated molds is complex. If the component is also to fulfill optical functions, special know-how is required. Only if the design rules are adhered to and at the same time all specifications for achieving optical quality are taken into account, will functioning mold concepts be created.
With us, part and mold design are in the hands of one team. This ensures the transfer of all relevant information and knowledge. Modern design and simulation software supports fundamental decisions, for example on the choice of gating system, mold temperature control, molded part output and molded part separation. We use filling simulations to analyze critical issues, optimize processes and make our customers' projects even more cost-effective.

Mold making for optical applications

To ensure that injection molds can withstand maximum mechanical stresses, the choice of the right materials, modern machining methods and, above all, the experience of highly qualified mold mechanics are essential. And in the field of plastic optics, additional skills are required: To produce the optically effective surfaces, the high-precision mold inserts must meet the highest requirements for dimensional accuracy and surface quality. Manufacturing them is one of VIAOPTIC's core competencies. By means of submerged-arc machining such as turning, milling, flycutting and planing in up to four machining axes, free-form surfaces, finest linear and microstructures are introduced into the optical inserts.
From prototype tools to 2K series tools, we offer a wide range of tool options. Professional storage, maintenance and servicing guarantee a long service life and maximum performance.
