Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – a dedicated manufacturer of high-precision injection molded components for the automotive industry. With over seven years of experience since our establishment in 2017, we specialize in producing complex side slider molds for new energy vehicle (NEV) power window motor end covers. Our factory, spanning 1,000 to 3,000 square meters, is equipped with advanced injection molding machines and a skilled team of 51–100 employees. We are proud to hold the TS16969 certification, ensuring our production processes meet stringent automotive quality standards. This product, the Complex Side Slider NEV Power Window Motor End Cover, represents our commitment to zero-flash, micro-slot precision injection molding, delivering reliable performance for modern electric vehicles.
Our end cover is designed to be an integral part of the window regulator system, protecting the motor and ensuring smooth operation. By leveraging our expertise in complex side slider mold design, we achieve intricate geometries with tight tolerances, eliminating the need for secondary operations. The micro-slot feature allows for precise assembly with mating parts, while the zero-flash surface finish enhances sealing and reduces noise. This component is injection molded from durable engineering plastics, offering excellent heat resistance, mechanical strength, and long-term durability—critical for the demanding NEV environment.
Key Features & Technical Specifications
- Complex Side Slider Mold Design: Enables multiple undercuts and intricate internal geometries in a single molding cycle, reducing part count and assembly cost.
- Zero Flash Technology: Precision mold cavity and core alignment ensure no excess material on the parting line, saving post-processing time and improving aesthetics.
- Micro Slot Precision: Tight dimensional control (tolerance up to ±0.02mm) guarantees proper fit with the motor housing and gear train, minimizing vibration.
- Material Options: Available in PA66+GF, PBT, or other customer-specified engineering grades, offering balanced strength, stiffness, and thermal stability (continuous use up to 150°C).
- TS16969 Certified Production: Our quality management system ensures consistent part-to-part repeatability, traceability, and defect prevention.
- Customizable Colors and Markings: We can match your specific color code and add laser marking or embossing for part identification.

Frequently Asked Questions (FAQ)
-
Q: What materials are available for this end cover?
A: We commonly use PA66+30%GF, PBT+GF, or other engineering plastics as per your drawing. Materials with UL94 V-0 flame retardancy are also available on request. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for this precision component is typically 5,000 pieces for initial orders. Lower quantities may be considered for sampling or pilot runs. -
Q: How long is the lead time for mold making and first samples?
A: For a new complex side slider mold, tooling takes approximately 30–45 days. Sample delivery follows within 7–10 days after mold trial. Production lead time for bulk orders is 3–4 weeks. -
Q: Can you match my specific color or add logo marking?
A: Yes, we can match any RAL or Pantone color. Laser marking, inkjet printing, or embossing for part numbers/ logos is available. -
Q: Do you have quality testing equipment to ensure the micro slot precision?
A: Absolutely. We use CMM, vision inspection systems, and profilometers to measure critical dimensions, ensuring ±0.02mm tolerance on slot width and depth. -
Q: Is this product suitable for high-volume production?
A: Yes, our multi-cavity molds and automated processes are designed for volumes up to 1 million parts per year. Mold will be maintained to last 500,000+ shots. -
Q: Do you provide support for design optimization?
A: We offer DFM (Design for Manufacturing) analysis to improve moldability, reduce flash, and enhance part strength. Our engineering team works closely with your designers. -
Q: What packaging do you use to protect the end covers during shipping?
A: Each part is individually packed in anti-static trays or boxes with EPE foam inserts, ensuring no scratches or deformation during transit.
