Passenger Airbag (PAB) Deployment Cover injection mold

Core Advantages

• Precision Molding Technology: Optimized gating systems and cooling channel designs address the challenges of thin walls and sensitivity to flow marks, ensuring finished parts are free of weld lines and possess high surface finish quality, meeting Class A surface standards.
• Customized Design Capability: We provide fullprocess customization from mold flow analysis to structural design, tailored to specific vehicle platforms and dashboard structures, including variations for lefthand and righthand drive configurations.
• LongLife Mold Manufacturing: Utilizing premium mold steel and standardized heat treatment processes, the molds are built to international standards (DIN/HASCO), offering a long service life suitable for mass production with low maintenance costs.
• OneStop Delivery Service: We offer a complete process chain from mold design and manufacturing to injection production, ultrasonic welding, and component assembly, simplifying supply chain management for our clients.

Product Features

• Structural Complexity: Features complex ejection mechanisms or angled lifters to solve demolding challenges of undercuts on the inner side of the cover, while maintaining precise thickness control of the airbag tear line.
• Surface Treatment: Mold cavity surfaces support grain etching, texturing, or highgloss polishing. The injected parts can match the overall texture of the instrument panel for seamless visual integration.
• Material Adaptability: Suitable for processing TPO, PP, ABS, and other common automotive interior materials, providing excellent weather resistance and aging performance.
• Testing Standards: Products undergo strict dimensional tolerance inspection, falling ball impact tests, and highlow temperature environmental testing to ensure structural stability under extreme conditions.

Application Scenarios

• Passenger Vehicle Manufacturing: Widely used in the rightside passenger airbag area of sedans, SUVs, and MPVs.
• New Energy Vehicles (NEV): Adapts to the minimalist interior design trends of NEVs, meeting requirements for lightweight and highstrength plastic components.
• Automotive Parts Supply: Provides supporting molds and injection components for Tier 1 automotive suppliers for the assembly of airbag modules.

FAQs and Solutions

Q1: How do you address visible weld lines or flow marks on the passenger airbag cover surface?
Solution: Weld lines affect aesthetics and can cause stress concentration. Our engineers utilize mold flow analysis software to optimize gate locations and adjust injection speed and pressure parameters. We also implement cold slug well designs to effectively eliminate weld lines, ensuring a smooth and uniform surface finish.

Q2: How is the uniformity of the tear line thickness ensured in the mold?
Solution: The tear line (weak line) is the technical core of the airbag cover. During mold manufacturing, we use highprecision Electrical Discharge Machining (EDM) and strictly control the machining depth tolerance to micron levels. We also perform 100% inspection using Coordinate Measuring Machines (CMM) to ensure the tear line ruptures accurately upon impact while maintaining structural integrity during normal use.

Q3: How do you ensure the molds exported to Europe meet local maintenance standards?
Solution: With over 15 years of export experience, our mold designs fully comply with DIN standards. We utilize standard components (such as ejector pins, springs, slider components) compatible with DME or HASCO standards, facilitating easy local replacement and maintenance for customers, thereby reducing postsale maintenance complexity.

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.
