Plastic Multi-Tube Connector Injection Mold Parts

Core Advantages

• Complex CorePulling Technology: Addressing the multidirectional hole structure of manifold fittings, the mold utilizes linked sliders or cylinderdriven angle lifters to achieve synchronized multidirectional demolding, guaranteeing the dimensional accuracy of threads and connection ports.
• Flow Channel Optimization: Gate locations are optimized through mold flow analysis to prevent weld lines from being located at critical stress points, enhancing the pressure resistance and impact strength of the connector.
• Air Tightness Assurance: The machining precision of molding components reaches the micron level, ensuring the injection part's sealing groove fits tightly with Orings. Products pass airtightness testing, preventing fluid leakage.
• Export Standard Manufacturing: Leveraging 15 years of export experience, mold components use international standard brands like DME and HASCO, offering easy maintenance and compliance with major global industrial standards.

Product Features

• Pressure & Temperature Resistance: Adapted for engineering plastic materials, injection parts maintain structural stability in hightemperature and highpressure environments without deformation or bursting.
• Chemical Stability: Materials feature resistance to acid, alkali, and oil corrosion, adapting to complex industrial fluid environments.
• Easy Installation: Interface dimensions comply with ISO or DIN standards, supporting various connection methods such as pushtoconnect, threaded, or bonding, with strong interchangeability.
• Molding Quality: Product surfaces are free of flash and sink marks. Runner residue is precisely controlled, reducing postprocessing steps.

Application Scenarios

• Automotive Fluid Systems: Used for multiport connections in automotive cooling water pipes, fuel lines, and brake air circuits.
• Industrial Pneumatic & Hydraulic: Suitable for air pipe connection and distribution control of cylinders and solenoid valves in automation equipment.
• Water Treatment Equipment: Used for pipeline transition nodes in water purifiers, pipeline pumps, and irrigation systems.
• Medical Equipment: Used for multichannel connection components in medical infusion lines and analytical instrument flow systems.

FAQs and Solutions

Q1: The multiport connector cracks or deforms under pressure. What is the cause?
Solution: This is usually caused by insufficient weld line strength or uneven material shrinkage. During the mold design phase, we optimize the melt flow path through mold flow analysis to move weld lines to non-stress areas. Simultaneously, we optimize the cooling system to eliminate internal stress at the junction of thick and thin walls, improving the product's overall pressure resistance.

Q2: The connector thread port has a large fit gap, leading to water or air leakage after installation. How is this resolved?
Solution: Thread precision directly determines sealing. We use high-precision EDM for forming threads and perform strict dimensional inspections and trial assembly. For materials with different shrinkage rates, we precisely set shrinkage compensation parameters to ensure the injection molded thread screws tightly with standard pipe fittings.

Q3: The mold slider mechanism wears out during long-term production, causing flash on products. How should it be maintained?
Solution: Mold sliders are made of wear-resistant steel and surface quenched. The design uses standard slider components, and replaceable inserts are designed for wear-prone areas. We provide detailed maintenance manuals and spare parts lists with the mold. Customers can regularly check the fit between the locking wedge and slider according to the guide, adjusting or replacing parts in time to extend mold life.

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.
