Medical device OEM required a transparent LSR sleeve with wall thickness 0.4–0.6mm, zero visible parting lines, and USP Class VI biocompatibility for a handheld diagnostic probe.
Selected Platinum-cured 30A LSR with high optical clarity. Engineered cold-runner 4-cavity mold with vacuum-assisted injection to eliminate short shots at 0.4mm wall section.
Wall thickness consistency ±0.03mm. Zero visible parting flash. Passed USP Class VI and cytotoxicity testing. 2M units delivered with 0 customer quality complaints.
DFM Analysis: Cold runner system eliminated waste — 100% material utilization. Wall-thinning risk zones pre-validated via Moldflow shrinkage simulation.
Our engineers work from your CAD drawings before any tooling begins — identifying potential failure modes, proposing material alternatives, and validating gate/cooling layouts digitally. This eliminates costly mold revision cycles.
Physical test results from production samples — available with every shipment on request.
