Ningbo Zhaoxu Plastic Products Co., Ltd. undertakes mold development and injection molding processing for router housings and network communication equipment housings. We support custom manufacturing from drawings, custom production from samples, and injection molding with customer-supplied molds and materials. Integrating custom plastic mold development, precision injection molding and finished product assembly, we provide one-stop injection molding services from mold opening to mass production for network equipment manufacturers, communication equipment enterprises, smart home brands, trading and e-commerce customers.

      Router housings serve to protect internal mainboards, chips, antennas and interface components. High requirements are placed on structural strength of the shell, heat dissipation hole arrays, antenna post mounting positions, precision of interface cutouts, assembly gaps between upper and lower shells, surface texture and consistency in mass production. We can complete mold design, machining, mold trial, mass production and supporting post-processing according to customer drawings or physical samples.

      The factory is located in Fanci Mold City, Longshan, Cixi, Ningbo, with a production area of 2000 square meters, divided into independent mold workshop, injection molding workshop and assembly workshop. The mold workshop is equipped with CNC machining centers, high-speed engraving and milling machines, large gantry equipment and other processing machines. Haitian injection molding machines equipped with servo manipulators and production monitoring devices are adopted in the injection workshop to carry out stable mass production.

Product Processing Advantages

      1. Integrated mold opening & injection molding service. With in-house mold and injection workshops, the whole process including mold design & fabrication, injection production and finished assembly is completed internally. Customers do not need to coordinate multiple suppliers, which facilitates project progress tracking and quality control.

      2. Complete in-house mold processing equipment. All mold processing procedures are completed independently to reasonably control mold development cycle and update project progress in a timely manner.

      3. Automated injection production. Machines are equipped with servo manipulators and production monitoring systems to reduce human interference and maintain consistent appearance and dimensions of products across batches.

      4. A variety of engineering plastics available, including PP, ABS, PC, ABS+PC alloy, etc. We provide proper material recommendations based on practical requirements such as drop resistance, snap toughness, transparent windows and impact resistance. PC can be used for transparent covers to guarantee light transmission; PP or ABS can be adopted for base shells to balance strength and cost.

      5. Focus on surface and assembly quality. By optimizing mold polishing, injection parameters and demolding scheme, common defects such as sink marks, flash, flow marks and mold lines are improved. Assembly gaps of shells, snaps and transparent covers are controlled to ensure smooth opening and closing of snaps.

      6. Supporting post-processing services available. Inspection, simple assembly, packaging and other follow-up procedures can be finished according to customer requirements, reducing customers’ workload of multi-party coordination and secondary processing.

Applicable Product Categories

      Injection molding of router housings.

      Mold opening and injection molding for wireless network equipment housings.

      Processing of upper and lower shell accessories for communication equipment.

      Injection molding for smart home gateway housings.

      Mold development for plastic housings of antenna mounting bases.

Common Material Guide

      ABS: Good moldability, easy surface texturing, moderate cost. Flame-retardant grades optional, widely used for ordinary router housings.

      PC: Excellent heat resistance, outstanding flame retardancy and high impact strength, suitable for network equipment housings with high fire safety and structural strength requirements.

      ABS+PC alloy: Balances toughness, heat resistance and flame retardancy with good dimensional stability, commonly used for mid-to-high end router and gateway housings.

      Final material selection is determined comprehensively by product structure, working conditions, flame retardant grade and safety standard requirements. Engineers can provide material selection suggestions.

Processing Workflow

      Customer submits requirements with drawings or physical samples→Feasibility assessment by engineers→Proposal and quotation issued for mutual confirmation→Mold design→Mold fabrication→Mold trial and sampling→Customer sample approval→Mass injection molding→Finished product inspection & packaging→Logistics delivery→After-sales technical support.

      During requirement evaluation, customers provide 2D/3D drawings or physical samples. Engineers analyze product structure, mold scheme and material selection. Quotation is normally available within 1‑2 working days.

      Mold design confirms key items including gates, parting surfaces, ejection structures and vent positions. Mold structure optimization is carried out for snaps and transparent parts.

      All mold procedures are completed in our own workshop, including CNC machining, polishing, mold fitting and mold trials.

      After mold trial, samples are inspected for dimension, appearance, snap operation and cover assembly. Mold adjustment will be performed if necessary, and mass production starts only after sample approval.

      Mass production adopts automated equipment with product sampling inspection during production.

      Finished products will be packed and shipped after inspection of appearance, dimension and assembly functions. Relevant production records can be provided on demand.

Quality Control

      Raw material grades and batches are checked upon incoming storage; material certificates can be provided for key raw materials.

      For each production batch, mass production will not start until the first article passes inspection on appearance, dimension and assembly functions.

      Periodic sampling inspection on product dimension, appearance and snap tightness during production; production process adjusted as required.

      Final inspection before shipment to reduce outflow of defective products.

      Product information of each batch can be traced back to production machines and raw material batches for convenient troubleshooting later.

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.

FAQ

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

A: Yes. Customization from samples is available. We can reverse-engineer based on physical samples and develop corresponding molds.

Q: Can router housings meet flame retardant requirements?

A: Yes. Confirm flame retardant grade in early communication and select corresponding flame-retardant plastic raw materials to meet safety standard requirements for network equipment.

Q: Can heat dissipation holes and logo marks on the housing be integrally formed directly by mold?

A: Yes. Hole and character structures are directly machined on the mold and formed in one injection molding step, eliminating subsequent processing procedures.

Q: What is the MOQ for router housing injection molding?

A: MOQ varies with product structure and mold scheme. Both small-batch trial production and large-volume orders are negotiable, subject to the confirmed quotation.

Q: Can housings be customized in different colors?

A: Yes. Housing color can be customized as requested. Flame-retardant materials also support color matching. Specific requirements can be confirmed in early communication.

Q: Will samples be provided for confirmation before delivery?

A: Yes. Samples will normally be available after mold trial. Mass production will be arranged only after customers verify sample dimensions, appearance, hole position accuracy and housing assembly performance.
