As a professional manufacturer specialized in precision injection molding, Changzhou Hongxinyutai Precision Mold Co., Ltd. proudly offers a custom injection molding service for auto water pump housings, utilizing high-performance PPS+GF30 material. Our advanced molding capabilities, combined with a strict tolerance of ±0.02mm, ensure that each water pump housing meets the demanding requirements of modern automotive cooling systems. With over 8 years of experience and a factory spanning 1,000–3,000 square meters, we are committed to delivering reliable, cost-effective parts that enhance engine performance and longevity.
Product Features and Technical Specifications
Our custom injection molding service is tailored to produce water pump housings that offer exceptional strength, thermal resistance, and dimensional accuracy. Below are the key characteristics:
Material Excellence: PPS reinforced with 30% glass fiber (PPS+GF30) provides outstanding mechanical strength, low moisture absorption, and high heat deflection temperature, making it ideal for under-hood automotive applications.
Precision Tolerances: ±0.02mm tolerance ensures consistent fit and function, reducing assembly issues and leakage risks.
Custom Complex Geometries: Our molds are engineered to handle intricate designs, including internal channels, bosses, and mounting flanges, all in a single shot.
High Productivity: Multi-cavity and family mold options are available to optimize cycle times and reduce per-part cost.
Surface Finish Options: Choose from standard textured, glossy, or matte finishes to meet aesthetic or functional requirements.
Rigorous Quality Control: Every batch is inspected using CMM (Coordinate Measuring Machine) and visual checks to verify dimensions and surface quality.

Frequently Asked Questions (FAQ)
Q1: What is the minimum order quantity (MOQ) for custom injection molding?
A: Our MOQ depends on part size and complexity. For water pump housings, typical MOQ is 1,000 pieces for mass production, but we also offer low-volume prototyping (100–500 pcs) upon request.Q2: Can you provide samples before mass production?
A: Yes, we offer T1 (first trial) samples after mold completion. Samples can be shipped for your approval before full production. Sample fees are negotiable and refundable with bulk orders.Q3: How long does it take to make a new mold?
A: Standard lead time for a water pump housing mold is 25–35 days, depending on cavity count and complexity. Rush service is available with additional charges.Q4: Does PPS+GF30 require special drying or processing conditions?
A: Yes, PPS is hygroscopic. We use dehumidifying dryers to ensure moisture contentQ5: Can you modify an existing mold design?
A: Absolutely. We can perform mold modifications such as adding inserts, changing gate locations, or adjusting core/cavity dimensions. A feasibility study is provided beforehand.Q6: What quality certifications do you hold?
A: Our quality system is certified to IATF 16949:2016 (automotive sector standard). Full inspection reports and material certificates are provided with each shipment.Q7: Do you offer assistance with product design or DFM (Design for Manufacturing)?
A: Yes, our engineering team provides comprehensive DFM analysis to optimize your part design for moldability, reducing costs and lead time. We offer suggestions for draft angles, wall thickness, and rib design.Q8: What payment terms are accepted?
A: We accept T/T, L/C, and Western Union. For new customers, typically 50% deposit with order and 50% before shipment. Long-term clients may negotiate more favorable terms.
