Ningbo Chaoxu Plastic Products Co., Ltd. undertakes mold development and precision injection molding services for automotive windshield washer hose connectors, plastic tee / straight / Y-type nozzle joints, supporting drawing-based mold making and sample-based reverse engineering. We integrate plastic mold R&D, engineering plastic injection molding, and supporting post-processing into one service, targeting the automotive parts and vehicle washer system industry, offering one-stop supporting services of product DFM evaluation, mold manufacturing, and batch injection molding.

      This product is an automotive windshield washer cleaning pipeline plastic connector, available in tee (T-type), straight, and Y-type branch structures. The joint outer circumference features multiple anti-slip barb structures for quick push-fit connection with rubber hoses, enabling washer fluid pipeline branching and transition. The product features high dimensional accuracy, stable roundness at insertion positions, and fits tightly with rubber hoses after assembly — no detachment or leakage under high-pressure water flow. It resists windshield washer fluid corrosion and high/low temperature aging, adapting to automotive engine bay environments. It is a key plastic connector in the windshield washer pipeline system. Mold design, trial molding, and mass production can be carried out based on customer 3D drawings or physical samples.

      The factory is located in Mould City, Fanshi, Longshan, Cixi, Ningbo, covering an area of 2,000 square meters, with independent mold workshop and injection molding workshop. The mold workshop is equipped with a full set of processing equipment including CNC machining centers, high-speed engraving and milling machines, EDM machines, and grinders. The injection molding workshop is equipped with Haitian injection molding machines with servo robotic arms, excelling in stable mass production of small precision automotive plastic parts.

Product Processing Advantages

      1. Integrated mold opening and injection molding — product structure evaluation, mold processing, trial molding and mold correction, and injection molding production are all completed in-house, reducing outsourced processes and facilitating control over delivery time and product consistency.

      2. Early-stage DFM manufacturability analysis — risk prediction for small slender insert joints, barb structures, and wall thickness uniformity; optimization of gate and venting solutions to prevent short shots, deformation, and sink marks, ensuring joint roundness.

      3. Multiple grades of engineering plastics available — PP, PA nylon, etc., resistant to washer fluid corrosion, with good toughness; barb structure has high strength and is not prone to fracture or detachment after repeated insertion and extraction.

      4. Precision mold processing with multi-cavity mold design to improve production efficiency; key focus on insertion barb and outer diameter dimensional accuracy to ensure interference fit with rubber water hoses for leak-proof performance.

      5. Complete quality control system — first article inspection, in-process patrol inspection, sampling inspection of joint outer diameter and insertion fit sealing performance, batch traceability, meeting automotive parts quality control requirements.

      6. Supporting post-processing — burr trimming, appearance sorting, packaging and shipping, reducing customer secondary processing workload.

Common Material Descriptions

      PP polypropylene: cost-effective, good toughness, resistant to washer fluid corrosion, not prone to brittle cracking at low temperatures — the mainstream material for wiper water pipe joints.

      PA nylon: better rigidity, higher temperature resistance, creep-resistant, suitable for high-temperature engine bay conditions; joints are less prone to deformation during long-term use.

      Material selection is determined comprehensively based on product temperature resistance, medium resistance, assembly strength requirements, and cost. Engineers provide material selection recommendations.

Processing Workflow

      Customer provides 3D drawings / physical samples → DFM product structure evaluation → Output solution quotation, confirmed by both parties → Mold structure design → Mold CNC/EDM processing, polishing and fitting → T1 trial molding → Samples sent to customer for confirmation → Mold modification per feedback → Batch injection molding after sample approval → Product inspection → Packaging and delivery → After-sales follow-up.

      During the requirement evaluation stage, customers provide drawings or physical samples, specify material, dimensional tolerance, and annual output requirements — quotation solution output within 1–2 working days.

      Mold design focuses on slender joints and barb structures, optimizes venting, and solves filling difficulties of small plastic parts.

      Trial molding tests appearance, dimensional accuracy, and water pipe insertion sealing; mass production starts after customer confirmation.

Quality Control

      Raw material incoming inspection verifies grade; material certificates available for engineering plastics.

      Dimension verification at each mold processing stage, with focus on key tolerances of insertion outer diameter and barb structure.

      Injection molding production implements first article inspection, scheduled in-process patrol inspections, and sampling tests for water pipe insertion and water flow leakage, monitoring defects such as deformation, short shots, and flash.

      Finished products undergo key inspection of appearance and dimensional accuracy; defective products are sorted and quarantined.

      Production records document machine and raw material batches for full traceability.

FAQ

Q: Can molds be made with only physical wiper joint samples but no drawings?

A: Yes, we support sample-based reverse engineering to generate 3D models before mold development.

Q: Will the barbs easily break when assembling with rubber hoses?

A: DFM optimizes barb fillets and wall thickness with high-toughness materials, ensuring they do not break easily during insertion and lock firmly after assembly.

Q: Can multi-cavity molds be made to increase capacity?

A: Yes, multi-cavity molds are designed based on product size and order quantity to reduce unit cost.

Q: Does automotive wiper plastic joint injection molding support small-batch trial production?

A: After mold acceptance, we support everything from small trial orders to large batch orders.

Q: Are samples provided for confirmation before mass production?

A: Yes, samples are provided after trial molding. Mass production starts only after customer verifies dimensions and assembly sealing performance.
