Plusoptix GmbH has been developing and manufacturing handheld, binocular photorefraction devices since 2001 and its devices are available in more than 60 countries worldwide. The company’s devices assist ophthalmologists, opticians, paediatricians and health authorities with the early diagnosis of the most common vision disorders in children. Today, Plusoptix is the world leader in binocular photorefraction.

the starting point:
New partner for new model range
Plusoptix needed support with producing a new model range of photorefraction devices. The company was looking for a manufacturing partner not only to produce the components, but to provide advice on design as well. Given our impressive list of satisfied customers and our longstanding experience in both mould making and injection moulding, Plusoptix GmbH chose to work with toolcraft.
the challenge:
Guaranteeing optimum functionality
When making the mould, the first step was to decide whether undercutting would involve an inner slider or forced ejection. Eventually, the forced ejection method was chosen to save on costs and prevent the components from being soiled during the injection moulding process. A further requirement was ensuring that the components were completely free from any visible smears and sink marks. Steps also had to be taken to make sure the individual components fitted precisely so that the screw connection and catch on the closing mechanism would work properly.
The approach:
Excellent advice from start to finish
- Putting together a well-rounded project team (mould making and injection moulding)
- Advising the customer on how to process and design products suitable for being made from plastic
- Designing and building three injection moulds
- Manufacturing the injection-moulded parts
- Performing quality assurance using optical measurements (GOM)
the results:
Optimisation and reduction
During the product design process, toolcraft optimized the geometry of the battery cover in the housing, eliminating one assembly step and thereby reducing the overall manufacturing costs. The customer’s requirements were met in full and the new model range was launched to market as planned.
