K-STONE – Parking Air Conditioner Supplier in China

Plastic Intake Manifold Supplier

We are a professional wholesaler of plastic intake manifolds.Our plastic intake manifolds have been certified under the IATF 16949 and ISO 9001 core management systems.Given that plastics involve chemical composition and recyclability,our products have obtained UL certification,REACH and RoHS declarations,and have been registered and declared in the IMDS system with assigned ID numbers;as a result,they are approved for sale in European and American markets.

Durable Plastic Intake Manifolds From China

Our Ability

Advanced R&D and CAE Simulation

Advanced R&D and CAE Simulation

We possess robust synchronous development capabilities,utilizing CATIA and UG for 3D modeling.Our engineering team leverages high-fidelity CFD (Computational Fluid Dynamics) and Moldflow analysis to optimize airflow efficiency and structural integrity,ensuring designs meet the thermal and mechanical demands of modern engines before physical prototyping.

Precision Manufacturing and Specialized Welding

Precision Manufacturing and Specialized Welding

Our facility is equipped with high-tonnage precision injection molding machines specifically for PA66+GF30 materials.We specialize in Vibration Friction Welding,a critical process that ensures high-strength,leak-proof bonding of complex manifold halves.This expertise guarantees that every unit can withstand extreme burst pressures and long-term vibration.

Stringent Quality Assurance & Traceability

Stringent Quality Assurance & Traceability

Operating under the IATF 16949 quality management system,we implement a "zero-defect" strategy.Each manifold undergoes 100% automated leakage testing and CCD vision inspection on the assembly line.Furthermore,we provide full lifecycle traceability,from raw material batches to final delivery,ensuring total accountability.

Global Compliance and Supply Chain Excellence

Global Compliance and Supply Chain Excellence

We are experts in international standards,providing full material data via the IMDS system.Our products are fully compliant with REACH,RoHS,and EPA/CARB regulations,facilitating smooth customs clearance and environmental auditing.With ISO 14001 certification,we demonstrate a commitment to sustainable and socially responsible manufacturing for global partners.

How To Order?

As a responsible plastic intake manifold wholesaler,based on our years of experience,you should provide us with:
Please provide the specific engine model,OE number,and material of the vehicle.For custom development,please provide 3D data in STP/STEP or IGS format,as well as 2D PDF drawings with specified dimensional tolerances.Please feel free to contact us at any time or send an email to [email protected]. We’d be happy to assist you.

Quality & Validation

Test
Quality & Validation

For plastic intake manifolds,quality and validation are key to ensuring their long-term reliable operation under high-temperature,high-pressure,and high-vibration conditions.

Test
Burst Pressure Test

Ensure that the manifold can withstand at least 3 to 5 times the operating pressure (typically 4 to 6 bar or higher,depending on the engine type) to withstand backfire impacts.

Test
Leakage Test

Use the helium or air pressure drop method to ensure that vibration-friction welded joints achieve 100% leak-tightness.

Quality System

As a professional manufacturer of plastic intake manifolds in China,we ensure traceability and process control at every stage—from raw material receipt to finished product shipment—in compliance with the IATF 16949 standard.We verify that plastic pellets,seals,and inserts are free of hazardous substances and comply with IMDS,REACH,and RoHS certifications.We adopt a zero-defect strategy and incorporate Poka-Yoke (error-proofing) design into our injection molding and welding processes to prevent assembly errors.

Quality & Validation

Test
Thermal Aging

Subject the material to continuous cycling at temperatures ranging from 120°C to 150°C to verify that the decline in strength remains within acceptable limits.

Test
Vibration & Fatigue
Simulate resonance at different engine speeds to ensure that the mount and main housing do not fracture.
