Ningbo Zhaoxu Plastic Products Co., Ltd. undertakes mold development and precision injection molding for GPS Beidou positioning terminal housings. We support mold development from drawings, 3D scanning & reverse engineering from samples, injection production with customer-supplied materials or molds. Integrating plastic mold R&D, precision injection molding and supporting post-processing, we provide one-stop services including DFM evaluation, mold manufacturing and mass injection molding for IoT, vehicle electronics and security positioning manufacturers.

      GPS Beidou positioning housing is an IoT electronic enclosure built with mainboard, battery and antenna components. Key requirements include premium surface texture, closing gap between upper and lower shells, assembly feel of snaps, strength of screw posts, waterproof groove structure (if applicable), uniform wall thickness, anti-warpage and in-mold logo forming. Dimensional accuracy directly affects PCB assembly, sealing performance and overall device stability. We can complete mold design, mold trial and mass production based on customers’ 3D drawings or physical samples.

      The factory is located in Fanci Mold City, Longshan, Cixi, Ningbo, covering an area of 2000㎡ with independent mold workshop and injection molding workshop. The mold workshop is equipped with full processing equipment including CNC machining centers, high-speed engraving and milling machines, EDM machines and grinders. The injection workshop adopts Haitian injection molding machines equipped with servo manipulators, capable of stable mass production of precision plastic parts for consumer electronics.

Product Processing Advantages

      1. Integrated mold opening and injection molding. Product structure evaluation, mold processing, mold trial & revision and injection production are all finished in-house to reduce outsourced processes, making lead time and product consistency easier to control.

      2. Pre-project DFM manufacturability analysis. Risk assessment for snaps, joint lines, screw posts, sealing grooves and antenna avoiding grooves. Structure optimization in advance to prevent housing warpage, large assembly gaps and snap breakage.

      3. Multiple plastic grades available, including ABS, ABS+PC and PC. Matte / high-gloss surface options available to meet drop resistance and flame retardant requirements for vehicle-mounted and outdoor IoT devices. Logos can be integrally formed inside the mold.

      4. Precision mold machining. Tight tolerance control for joint lines and positioning posts of upper and lower shells to ensure uniform closing gaps and stable snap opening & closing feel.

      5. Complete quality control system. Material certificates can be provided for raw materials. First article confirmation, in-process patrol inspection and key assembly dimension testing are implemented with full batch traceability.

      6. Supporting post-process services, including appearance inspection, simple assembly and package delivery to reduce customers’ secondary processing workload.

Common Material Guide

      ABS: Good moldability, matte / high-gloss surface optional, cost-effective. Preferred for regular indoor positioning housings.

      ABS+PC: Impact resistant, temperature resistant and dimensionally stable, suitable for vehicle-mounted and outdoor positioning terminal housings.

      PC: High impact resistance and flame retardant, fit for positioning device housings with high strength and safety standard requirements.

      Material selection is comprehensively determined by application scenario, flame retardant grade, appearance requirements and cost. Engineers provide material recommendation.

Processing Workflow

      Customer provides 3D drawings / physical samples → DFM product structure evaluation → Proposal and quotation issued for mutual confirmation → Mold structural design → Mold CNC/EDM machining, polishing and mold fitting → T1 mold trial → Sample delivery for customer confirmation → Mold revision and adjustment based on feedback → Mass injection molding after sample approval → Product inspection → Packaging & delivery → After-sales follow-up.

      During requirement evaluation, customers provide drawings or physical samples and specify appearance, material and annual output requirements. Quotation will be available within 1‑2 working days.

      Mold design focuses on joint lines, snaps, screw posts and logo recesses. Machining starts after design approval.

      Mold trial inspects appearance, dimensions and assembly gaps. Mass production will be launched only after customer approval.

Quality Control

      Raw material grades are checked upon incoming storage; material certificates are available.

      Dimensional verification in each mold machining procedure. Key tolerances of joint lines, snaps and screw posts are strictly controlled.

      First article inspection and periodic patrol inspection are carried out during injection production to monitor defects such as warpage, sink marks and flash.

      Finished products are mainly inspected on mating surface, appearance and snaps. Defective goods are sorted and isolated.

      Production records include machine number and raw material batch to realize batch traceability.

Factory Profile

      The factory covers approximately 2000 square meters with separate workshops for mold, injection molding and assembly.

      Mold equipment includes more than ten sets of CNC machining centers, high-speed engraving and milling machines and large gantry equipment.

      Injection molding equipment are Haitian injection machines equipped with servo manipulators and high-definition monitoring systems.

      The core engineers have 25 years of plastic molding experience and 15 years of auto parts quality control experience, with supporting service experience for OEM manufacturers. Mature quality control experience can be applied to the processing of tool storage boxes and industrial plastic boxes.

      The factory is located in Fanci Mold City, Longshan Town, Cixi, Ningbo, close to National Highway 329 with convenient logistics and transportation.

FAQ

Q: Can you develop molds if I only have physical GPS positioning housing samples without drawings?

A: Yes. We support 3D scanning and reverse engineering from samples to generate 3D models for mold development.

Q: Can I get matte black appearance for the housing?

A: Yes. Corresponding texture etching will be done on mold surface to directly obtain matte housing after injection molding; post-spraying service is also available.

Q: Can logo marks on the housing surface be formed directly by mold?

A: Yes. Concave and convex characters can be engraved on mold insert for integral in-mold forming; laser engraving and silk screen printing after molding are also supported.

Q: Does injection molding for tracker housing support small-batch trial production?

A: After mold acceptance, we accept orders from small trial batches up to mass volumes.

Q: Will samples be provided for confirmation before mass production?

A: Yes. Samples will be provided after mold trial. Mass production starts only after customer approval.
