Application: Spring-activated piston for medical micro-pump system
The customer had designed a control valve with a spring-activated thermoplastic piston, sealed with two standard silicone O-Rings. They turned to Trelleborg Healthcare & Medical for assistance to analyze and resolve a leakage problem, while also aiming to reduce friction within the system.
Trelleborg Healthcare & Medical engineers partnered with the customer every step of the way to replace a poorly performing 3-piece piston assembly with a new multi-component solution:
Partnership during the design phase led to collaboration on product and component design, materials selection, manufacturing.concept development as well as validation.
The new, multi-component LSR part solved leakage and friction issues and provided a fully functional and reliable design.
The integration of three individual components into a single one eliminated steps in the customer's supply chain and manufacturing process, and thereby led to an increase in the customer's product quality and reliability at reduced production risk and overall lower costs.
