A global manufacturer of garden implements and motorised tools has invested in an automated plastic injection moulding and finishing solution for its US production facility to ensure consistent quality for critical engine components. Geometrically complex parts are now de-flashed using a Röslerswing blast chamber, which is fully integrated into the manufacturing line to enable continuous, automated processing.
The German-headquartered company produces its tools and equipment at facilities worldwide and is recognised for the high quality and reliability of its products used in forestry, landscaping and construction. However, two thermoset engine components previously sourced from external suppliers for the US plant did not consistently meet the required quality specifications.
To address this issue, the manufacturer decided to bring production of these parts in-house, including the removal of moulding flash generated during injection moulding. Drawing on positive experience with Rösler technologies in Europe, the project team worked with the company’s US subsidiary to develop an automated de-flashing solution.
The resulting system is based on the RWS 1200 swing chamber machine, specifically designed for the gentle processing of thermoset and highly filled thermoplastic components. The compact RWS 1200-I4-SAT2 machine features two chambers, each equipped with rotating satellite stations that securely hold the components during blasting. This dual-chamber configuration allows loading and unloading to take place in one chamber while de-flashing occurs in the other, effectively eliminating non-productive downtime.
Robotic handling ensures precise placement of the components on dedicated fixtures, while multiple blast nozzles accelerate non-abrasive media on to the rotating parts to remove flash and contaminants. The system achieves a cycle time approximately 15 seconds faster than the 60 seconds specified, reducing energy consumption and operating costs while ensuring reliable, high-quality component finishing.
