Plastic Car Water Pump Housing Mould

Product Parameter

Product Overview

1. Application Positioning

Suitable for mechanical and electronic water pump assemblies in the engines of passenger cars and light commercial vehicles, Plastic Car Water Pump Housing Mould can be directly assembled at the front end of the cylinder or in the electric drive system cooling loop, achieving over 35% weight reduction and eliminating the risk of electrolytic corrosion.K-SHOW is a professional manufacturer and supplier of plastic molds. Welcome to consult.

2. Material Solution

KSHOW Advantage

1. 20 Years of Cooling System Mold Experience

Since delivering the first water pump volute mold in 2003, over 340 cooling system injection molds have been completed, familiar with IATF 16949 and VDA 6.3 process requirements, with a customer repeat order rate of 80%.

2. Vacuum-Assisted Ejection System

Establishes 0.7 bar vacuum inside the Plastic Car Water Pump Housing Mould, eliminating volute surface sticking and ejection marks, reducing ejection force by 30%, ensuring complete demolding of complex profiles without surface scratches.

3. 3D Conformal Cooling + High-Pressure Water Temperature Machine

Conformal cooling channels increase cooling efficiency by 40%, with thermal deformation of the bearing chamber ≤ 0.02 mm; in combination with a 120°C water temperature machine, it achieves controllable molding shrinkage and reduces cycle time by 4 s.

4. Corrosion-Resistant Powder Metallurgy Inserts

The high-pressure area of the volute and the sealing groove use 58 ±1 HRC powder metallurgy steel, with surface roughness ≤ 0.1 µm after DLC coating, and tripled resistance to glycol erosion.

5. Full-Cycle Maintenance Guarantee

From initial CFD flow optimization, prototype SLS functional validation to mass production ramp-up, on-site debugging within 48 hours is provided; within five years after mold delivery, the prices of hot runner and vacuum system spare parts are locked, and spare parts warehouses in East China and Central China can ship within 24 hours.
