Key Benefits
- Drip-free dispensing — engineered cross-slit geometry prevents leaking and stringing.
- Food-safe LSR — neutral taste, BPA-free, easy to clean.
- Consistent flow control — tuned slit stiffness for targeted viscosity ranges.
- Long service life — excellent elastic recovery and fatigue resistance.
- OEM-ready — size, hardness (Shore A), color, and packaging customizable.
- Easy assembly — designed for push-fit or snap-in bottle cap integration.
Production Process (professional, concise)
- Material selection & compounding — select medical/food-grade LSR; compound to required Shore A hardness and color stability.
- Mold design & validation — 3D CAD, Moldflow analysis, precision molds for consistent cross-slit geometry.
- LSR injection molding / transfer molding — high-precision LSR injection into heated mold cavities; controlled cure cycles.
- Cross-slit finishing — precision knife/laser slit or mold-formed slit; process selected by volume and finish requirements.
- Post-cure & cleaning — thermal post-cure to stabilize properties, followed by ultrasonic cleaning if required.
- Quality testing — leak/drip tests, flow-rate verification over viscosity range, dimensional inspection (CMM), and hardness checks (durometer).
- Traceable packing & labeling — batch traceability, sanitized packing, custom labeling for OEM clients.
- Logistics & shipping — FOB Xiamen or delivered per client incoterms.
Quality Assurance
We perform full incoming material verification, in-process monitoring, and final inspection including CMM dimensional checks, functional leak/pressure testing, hardness verification, and compliance testing to requested standards (FDA/LFGB/SGS). Each batch is traceable and shipped with QC reports upon request.
Factory Overview
Our production site is equipped with advanced LSR molding cells and precision tooling capabilities — including CNC mold machining, Mirror EDM, and slow-speed wire-cut for mold accuracy. We operate multiple LSR injection units and support lines for finishing, ultrasonic cleaning, and automated inspection. ISO 9001 certified QC teams use 3D projectors, durometers, and automated leak testers to ensure consistent, OEM-grade output and fast prototyping to mass production scaling.
