Sensor Injection Molded Components
Custom injection-molded housings, flow channels, covers and connection structures for ultrasonic flow sensors and other sensing assemblies. JingZhan supports DFM, mold development, material selection, prototyping and stable production for components requiring reliable fit, sealing and repeatable assembly.
Product Overview
JingZhan supports custom injection-moulded covers, bases, retaining rings and related parts for sensor assemblies. Reviewing the component set together helps connect internal positioning, enclosure fit and repeat-order requirements before tooling is released. The photographs show plastic and mating-component examples, not a standard finished sensor offered with one shared performance specification. DESIGN AND MANUFACTURING Supply the PCB, sensing element, cable and mating-part data where relevant. Define supports, locating datums and assembly clearances so moulded features position components without unintended interference. Review the cover, base, retaining features and any seal interface as a set. Agree closure, retention and leak-test requirements using the actual assembly. The presence of a seal or ring in a photograph does not establish an ingress rating. Match the approved grade to stiffness, dimensional stability, temperature and chemical exposure. Define colour, transparency or any electrical-performance requirement separately, with an appropriate test and acceptance scope. Review wall balance, filling, cooling and demoulding around bosses, clips and slender features. Set cavity identification and agreed dimensional/appearance checks where needed to keep repeat batches on an approved baseline. TECHNICAL SPECIFICATIONS PRODUCTION AND REPEAT SUPPLY JingZhan's listed CNC/EDM toolroom, injection-moulding presses and dimensional/vision inspection equipment provide process options for different housing geometries. The quotation defines the route for each part and selects a press for the resin, shot volume and tool. Electronics integration, sealing operations, calibration and functional sensor testing must be separately scoped if required. Approve the component revisions, resin, samples and inspection plan before regular supply. Keep identification and release quantities aligned for coordinated parts. Record relevant repairs and review changes affecting mounting, retention or sealing interfaces before the next production batch is released. Tooling investment is quoted separately from the piece price. Share annual demand and release quantities so cavity count, procurement and batch cost can be reviewed together. RELATED APPLICATIONS Plastic enclosure and locating-component development for liquid-flow or bubble-sensing modules. Custom sensor-module housings integrated into industrial or laboratory equipment. Related covers, bases and retaining parts supplied for customer-designed monitoring assemblies. The delivered plastic parts do not automatically include the pictured wiring, seals or electronics. Finished-sensor accuracy, electrical characteristics, environmental ratings and application approval are confirmed for the customer's complete system and agreed supply scope. Discuss your drawing and supply requirements. Send CAD, resin preference, critical features, annual demand and release quantity.

Basis for quotation
DFM review
Indicative 3–5 working days after complete drawings and requirements.
New tooling
Indicative 4–8 weeks to first mould trial after tool-design approval and commercial release; corrections and customer validation are additional.
Order quantities
Initial quotation-planning basis: a 500-piece pilot or 1,000-piece repeat batch per part number, resin and colour, subject to project quotation.
Repeat orders
Indicative 10–15 working days after materials and the production slot are confirmed. Customer qualification, special processing and transit are additional.
Keep repeat orders on an approved baseline
