Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. As a dedicated manufacturer founded in 2017, we specialize in crafting high-performance precision injection molds for demanding applications. Our Precision Injection Mold for Motor Bobbin Insulation Parts is designed to deliver exceptional durability and accuracy, utilizing premium PPS material for the molded parts and German steel for the mold itself. With a guaranteed life of 300,000 shots, this mold ensures long-term reliability and cost efficiency for your motor insulation component production.
Our mold is meticulously engineered to produce bobbin insulation parts that meet stringent electrical and thermal requirements. The use of PPS (Polyphenylene Sulfide) provides excellent dimensional stability, high heat resistance, and superior electrical insulation properties, making it ideal for motor applications. The mold cavity is crafted from German steel (such as 1.2344 or equivalent), known for its high wear resistance, toughness, and ability to maintain tight tolerances over thousands of cycles.
Key Features & Technical Specifications
- Mold Life: 300,000 shots (minimum) under normal operating conditions, ensuring long production runs without frequent maintenance.
- Mold Material: High-quality German steel, heat-treated for optimal hardness and wear resistance.
- Part Material: PPS (Polyphenylene Sulfide) – compatible with various grades to meet specific insulation and thermal requirements.
- Precision Tolerances: ±0.01 mm on critical dimensions, ensuring consistent part quality and interchangeability.
- Cooling System: Optimized cooling channels to reduce cycle time and improve part quality.
- Ejection System: Robust design with guided ejector pins or plates for smooth part release.
- Gate Type: Customizable (e.g., side gate, pin gate) to suit part geometry and material flow.

Frequently Asked Questions
- What is the typical lead time for this mold? The standard lead time is 30–45 working days, depending on complexity and customization. We can expedite for urgent orders upon request.
- Can this mold be used for other materials besides PPS? While optimized for PPS, the mold can be adapted for other engineering plastics like LCP, PA9T, or PBT with possible adjustments to gate size and cooling. Please consult our team.
- What maintenance is required to achieve 300,000 shots? Regular cleaning, inspection of moving parts, and periodic re-polishing of the cavity may be needed. We provide a detailed maintenance guide with each mold.
- Do you offer mold trial services? Yes, we offer trial runs at our facility using your specified PPS material. A trial report with part measurements and photos is provided.
- Is the mold compatible with all injection molding machines? The mold can be designed with standard clamping holes and dimensions to fit most common machine brands (e.g., Engel, Arburg, Haitian). We require your machine specifications to ensure compatibility.
- What is the warranty period? We provide a 12-month warranty against defects in workmanship and materials, covering the mold base and cavities under normal use.
- Can you produce multi-cavity molds for higher output? Absolutely. We can design molds with 2, 4, 6, or more cavities depending on the part size and your production volume. The 300,000-shot life applies to each cavity.
- How do you ensure the mold meets insulation requirements? Our mold design includes proper draft angles, flash control, and dimensional accuracy to meet common insulation standards (e.g., UL 1446). We also support customer-specified testing.
