WHY PROCUREMENT TEAMS BUNDLE GASKETS & FILMS AT RUNHENG
Zero-Leak IP67 Housing Seals & High-kV Die-Cut Phase Barriers Under One Roof
01. Perfect Mating Fit with RUNHENG Covers
Because we tool and mold both the rigid plastic encoder/end covers and the elastomeric sealing gaskets in-house, perimeter tongue-and-groove compression ratios are 100% matched for IP65/IP67 ingress protection.
02. Low Compression Set & Oil/Heat Resistance
Molded in Silicone, NBR, EPDM, and FKM (Viton), our housing gaskets maintain long-term elastic recovery without flattening or leaking under -40°C to 200°C+ thermal cycling.
03. High-kV Die-Cut Insulating Films (0.12mm–0.5mm)
Clean, burr-free rotary and flatbed die-cutting of UL94 V-0 Mylar®/PET, Nomex® aramid paper, vulcanized fiber, and Kapton® polyimide films for stator slot liners, phase separators, and PCB barriers.
04. Consolidated BOM & Lower Sourcing Overhead
Source your bobbins, end caps, grommets, gaskets, and insulating sheets from a single ISO 9001 certified Foshan manufacturer—simplifying vendor management and guaranteeing assembly compatibility.
