Binocular photorefraction – Precision preventive care

the starting point – New partner for new model series
Plusoptix needed support for producing a new series of camera parts for children’s eye tests(Photorefractors). They sought a manufacturing partner who could also advise on design. Due to toolcraft’s long-standing expertise in mould making and injection moulding, Plusoptix chose toolcraft.

The Challenge – Guaranteeing optimum functionality
In mould making, a decision was needed between undercut sliders and forced demoulding. Forced demoulding was chosen to reduce costs and prevent contamination during moulding. Parts also had to be free of flow marks and sink marks. Precise fit was critical for screw and snap functions.

The Approach – Excellent advice from start to finish
An interdisciplinary team from mould making and injection moulding was formed. toolcraft advised on plastic-compatible design, built three moulds, and produced the parts. Quality control was performed using optical measurement (GOM).

The Result – Optimization and reduction
toolcraft optimized the battery cover geometry, eliminating an assembly step and reducing manufacturing costs. Customer requirements were fully met, enabling the new model series to launch as planned.
