Ningbo Chaoxu Plastic Products Co., Ltd. can undertake mold development and injection molding services for power adapter housings, supporting drawing-based customization, sample-based customization, and injection molding with customer-supplied molds and materials. The company integrates plastic mold custom development, precision injection molding, and finished product assembly, providing one-stop injection molding supporting services from mold opening to mass production for power supply manufacturers, electronic equipment enterprises, security equipment suppliers, and trading e-commerce customers.

      Power adapter housings are used to protect the internal circuit boards and electronic components. The products have high requirements for housing flame-retardant performance, structural strength, heat dissipation rib forming, screw boss hole accuracy, assembly clearance, and batch consistency. The company can complete mold design, processing, trial molding, mass production, and supporting post-processing based on customer drawings or physical samples.

      The factory is located in Mould City, Fanshi, Longshan, Cixi, Ningbo, with a 2,000-square-meter production site, 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 equipment. The injection molding workshop uses Haitian brand injection molding machines with servo robotic arms and production monitoring equipment, enabling stable batch production.

Product Processing Advantages

      1. Integrated mold opening and injection molding service — own mold and injection molding production workshops; mold design and manufacturing, injection molding production, and finished product assembly are all completed in-house, so customers do not need to coordinate with multiple suppliers, making project progress follow-up and quality control more convenient.

      2. Own complete set of mold processing equipment — independently complete each mold processing operation, helping reasonably control mold opening cycle and timely synchronize project progress.

      3. Automated injection molding production — equipment equipped with servo robotic arms and production monitoring system, reducing the influence of human factors and maintaining consistency of appearance and dimensions across different batches.

      4. Multiple engineering plastics available — flame-retardant grades such as ABS, ABS+PC alloy, and PC can be selected. Based on actual use requirements such as flame-retardant grade, temperature resistance, impact resistance, and surface texture, suitable material selection advice is provided. Heat dissipation ribs and logo characters on the housing can be integrally molded.

      5. Focus on product dimension and appearance quality — by optimizing mold polishing, injection process parameters, and ejection solutions, common problems such as sink marks, flash, flow marks, and deformation are improved. The accuracy of screw bosses, positioning holes, and upper/lower shell assembly flanges is strictly controlled to ensure the housing closes tightly.

      6. Supporting finished product post-processing services — inspection, simple assembly, packaging, and other subsequent processes can be completed according to actual customer needs, reducing the workload of multi-party coordination and secondary processing for customers.

Applicable Processing Categories

      Injection molding of power adapter housings.

      Mold opening and injection molding for charger plastic housings.

      Plastic part processing for switching power supply housings.

      Injection molding of adapter upper/lower shell accessories.

      Mold development for high-power power supply housings.

      Custom integrated molding of texture and logo for power supply housings.

      Customization of plastic housings for electronic power equipment.

      The above are conventional processing categories. Other power supply housings, charger shells, and non-standard electronic plastic parts can be discussed for customization feasibility based on drawings or samples.

Common Material Descriptions

      ABS: good molding performance, easy surface texturing, moderate cost, flame-retardant grades available, mostly used for ordinary power adapter housings.

      PC: excellent temperature resistance, outstanding flame-retardant performance, high impact strength, suitable for high-power power supply housings with high fire safety requirements.

      ABS+PC alloy: balances toughness, temperature resistance, and flame-retardant properties, good dimensional stability, mostly used for mid-to-high-end power adapter housings.

      Final material selection needs to be comprehensively determined based on product structure, working conditions, and safety certification requirements. Engineers can provide material selection references.

Processing Workflow

      Customer submits requirements, provides drawings or physical samples → engineers conduct feasibility evaluation → provide solution and quotation, confirmed by both parties → carry out mold design → mold processing and manufacturing → trial molding and sampling → customer confirms samples → batch injection molding production → finished product inspection and packaging → logistics delivery → after-sales technical follow-up.

      During the requirement evaluation stage, customers provide 2D/3D drawings or physical samples. Engineers analyze product structure, mold solution, and material selection, generally providing a quotation within 1–2 working days.

      Mold design confirms key contents such as gate, parting line, ejection structure, and venting position, and optimizes mold structure for heat dissipation ribs, logo characters, and screw boss positions.

      All mold processes are completed in the own workshop, including CNC processing, polishing, mold fitting, trial molding, etc.

      After trial molding, sample dimensions, appearance, clarity of texture and characters, and housing assembly fit are inspected. The mold is adjusted if necessary. Mass production starts only after sample confirmation.

      During the mass production stage, production relies on automated equipment, and product sampling inspection is carried out during production.

      After finished products pass appearance, dimension, and assembly function inspection, they are packaged and shipped. Relevant production records are provided as needed.

Quality Control

      Raw materials are checked for grade and batch upon storage; flame-retardant raw materials can be provided with relevant material certificates.

      For each production batch at machine start-up, the first article must pass appearance, dimension, and assembly function inspection before subsequent batch production begins.

      During production, product dimensions, hole tolerances, and housing assembly fit are sampled regularly, and production process is adjusted as needed.

      Finished products are inspected before shipment to reduce outflow of defective products.

      Each batch of product information can be traced back to the production machine and raw material batch, facilitating later problem troubleshooting and handling.

FAQ

Q: Can molds be made with only physical adapter housing samples but no drawings?

A: Yes, sample-based customization is supported. The physical sample can be measured and reconstructed, then the corresponding mold developed.

Q: Can power adapter housings meet flame-retardant requirements?

A: Yes, confirm the flame-retardant grade in advance and select corresponding flame-retardant plastic raw materials to meet relevant safety regulatory requirements.

Q: Can heat dissipation ribs and logo marks on the housing be directly integrally molded?

A: Yes, textures and characters are directly engraved on the mold and formed after injection molding, eliminating the need for subsequent silk-screen printing.

Q: What is the MOQ for power adapter housing injection molding?

A: The minimum order quantity varies with product structure and mold solution. Both small-batch trial production and large-batch orders can be discussed. The final confirmation shall be subject to the quoted content.

Q: Can the housing be customized in different colors?

A: Yes, housing color can be prepared according to customer needs. Flame-retardant grade raw materials also support coloring; specific requirements should be confirmed in advance.

Q: Will samples be provided for confirmation before delivery?

A: Yes, samples are generally provided after trial molding. Mass production is arranged only after the customer verifies dimensions, appearance, texture, and assembly effect.
