Motorcycle Rear Mudguard Injection Mold

Core Advantages

• Large Curved Surface Molding Control: Targeting the large and thin-walled characteristics of rear fenders, the mold incorporates hot runner systems and cold slug wells to balance filling pressure, effectively resolving warpage deformation and surface sink marks common in large-scale injection parts.
• Surface Texture Consistency: The cavity surface undergoes high-precision texturing processes, ensuring uniform depth of graining and gloss levels on the molded part that meet vehicle aesthetic standards, avoiding texture discontinuity caused by machining errors.
• Customized Structural Design: Based on customer-provided 3D models, shrinkage rates are precisely calculated, and mounting hole and snapfit structures are optimized to guarantee the fit and assembly precision between the fender and the frame or swingarm.
• FullProcess Service Capability: Leveraging 15 years of mold export experience, we provide not only mold manufacturing but also injection production, plastic welding (e.g., welding fender to inner liner), and component assembly services for one-stop delivery.

Product Features

• Weather-Resistant Material Adaptability: The mold design is compatible with automotive-grade materials like PP and ABS. The molded parts possess good resistance to UV, high/low temperatures, and chemical corrosion, suitable for complex outdoor conditions.
• Structural Strength Optimization: The mold features internal structures for forming reinforcing ribs, enhancing the mechanical strength of the fender without increasing weight, and preventing fatigue fracture from driving vibrations.
• High Assembly Precision: Critical mold dimensions are controlled to micron-level tolerances, ensuring gap and flushness alignment with tail lights, license plate frames, and surrounding fairings meet assembly process requirements.
• LongLife Design: Key mold components use wear-resistant steel, complying with international DIN or HASCO standards, ensuring dimensional stability during long-term mass production.

Application Scenarios

• Two Wheeled Motorcycle Manufacturing: Suitable for the production of rear fenders for street bikes, underbones, scooters, and other vehicle types.
• All-Terrain Vehicles (ATV/UTV): Used for fender mold development for off-road models, meeting higher impact resistance requirements for harsh environments.
• Electric Vehicle/EMoto Parts: Adapting to mold requirements for new energy two-wheeler exterior parts, meeting lightweight and personalized design needs.
• Aftermarket & Modification: Providing customized mold development services for modification brands, supporting personalized textures and styling production.

FAQs and Solutions

Q1: How do you address surface weld lines on the motorcycle rear fender after injection, which affect aesthetics?
Solution: Weld lines are typically formed where multiple melt flows meet. During the mold design phase, we use mold flow analysis software to optimize gate locations and numbers, adjusting the melt flow path. Structurally, we add overflow wells to divert cold material away from the joint line, thereby eliminating visible weld lines and ensuring a smooth, aesthetic fender surface.

Q2: The fender mounting holes have a deviation with the frame, making assembly difficult. How is this improved?
Solution: This issue is often caused by inaccurate shrinkage rate calculation or machining errors. With extensive export mold experience, we accurately set shrinkage compensation parameters based on specific material characteristics. After sampling, we inspect part dimensions using CMM and perform finetuning adjustments on the mold to ensure mounting hole dimensions strictly fall within tolerance ranges.

Q3: How can maintenance parts be obtained for molds exported overseas?
Solution: Our mold designs fully comply with international standards. All wearable parts (such as ejector pins, springs, slider components) utilize standard component systems like DME or HASCO. Upon shipment, we provide detailed mold maintenance manuals and standard spare part kits. Customers can purchase universal standard parts locally for replacement without relying on the original factory, significantly reducing maintenance costs.

Q: 10. If I want to develop a product containing injection-molded parts, what kind of assistance can you provide?

We can provide full support ranging from product development review and structural design, to mold manufacturing, volume injection molding, printing, and assembly. We can collaborate with customers in the early stages of product development to optimize designs for cost reduction and improved manufacturability.

Q: 9.What is the company's quality policy?

The company always adheres to the quality policy of "Precision, High Efficiency, Forging Quality," and is committed to providing customers with high-quality services through advanced technology and an excellent management team.

Q: 8.What are your competitive advantages compared to other mold enterprises?

Our advantages lie in the combination of Singapore's precision mold technology, advanced production equipment (extensive imported CNC and injection molding machines), a comprehensive one-stop production process (from design to assembly), and a strict quality management system certified by IATF 16949.

Q: 7.Who are your main customers, and to which regions are the products exported?

We have established good cooperative relations with well-known companies, including UK's Land Rover and Triumph Motorcycles, domestic SAIC, Changan, ABB charging stations, and Japan's Tiger Corporation. Our products are exported to countries such as Japan, Europe, and the United States.
