Automobile ABS Wiring Harness Injection Mold

Core Advantages

• Precision Mold Manufacturing: With over 15 years of mold export experience, connector mold cavities are machined to micronlevel accuracy, ensuring connector insertion and extraction forces meet standards to avoid poor contact or looseness.
• Stable Material Performance: Utilizing modified engineering plastics with strong weather resistance and high flame retardancy tailored for the ABS system environment, the injected parts maintain stable physical properties in temperatures ranging from 40℃ to 125℃.
• Integrated Assembly Capability: Beyond injection production, we provide supporting services for plastic ultrasonic welding, heat staking, and wire harness component assembly, streamlining the customer's supply chain.
• Customized Development: We support customization based on customer drawings or 3D models and can cooperate with OEMs or Tier 1 suppliers to optimize mold structures for wire harness routing.

Product Features

• Insulation & Flame Retardancy: The plastic materials possess superior electrical insulation properties, with flame retardancy ratings complying with UL94 V0 standards, safeguarding automotive circuit integrity.
• Structural Sealing: Designed for engine compartment and chassis environments, the housings support the installation of rubber sealing rings. Mold structures ensure sealing groove dimensional precision to achieve IP67rated waterproof and dustproof effects.
• Chemical Resistance: Materials exhibit resistance to oils and salt spray corrosion, adapting to complex vehicle chassis conditions.
• Latch Connection Reliability: The connector latch structure design is verified through fatigue testing to ensure the connection remains secure under vehicle vibration conditions.

Application Scenarios

• ABS Braking System: Used for connector housings and protective brackets of the ABS control unit main harness and wheel speed sensor harnesses.
• Automotive Wiring Harness Assembly: Applicable to branch connectors and waterproof housings within engine harnesses and chassis harnesses.
• New Energy Vehicles: Applied to plastic structural components for electronic braking systems and electronic control unit signal transmission harnesses.
• Aftermarket: Providing standard specification harness connector injection parts for the automotive repair market.

FAQs and Solutions

Q1: What causes cracking or embrittlement in ABS wiring harness connector housings?
Solution: This is usually caused by improper material selection or unreasonable injection molding process parameters. We intervene in material analysis during the mold development stage, selecting glassfiber reinforced PBT or PA66 materials. We also strictly control drying times and melt temperatures during injection to eliminate internal stress, preventing cracking during later thermal cycling.

Q2: How do you adjust if the wire harness connector fits too tightly or too loosely with the mating terminal?
Solution: The fit precision of connectors relies on the dimensional tolerance control of the mold core and cavity. We use highprecision Wire EDM (slow wire cutting) and CMM inspection to correct (modify) key mold dimensions to the micron level. During the sampling phase, we perform insertion and extraction force testing to ensure the force values are within the standard range, guaranteeing connection reliability.

Q3: How is the welding strength of plastic components in the wire harness ensured?
Solution: We possess plastic welding and assembly capabilities. For wire harness fixing points and housing components, we employ ultrasonic welding technology and verify welding quality through peel strength testing. During mold design, energy directors are prereserved to ensure adequate melting depth and area, meeting wire harness pulltest requirements.
