Pressure-Bearing Structure
Tank shell wall thickness, dome shape and reinforcement ribs are reviewed for pressure resistance. Mold design considers filling pattern to avoid weak knit lines in stressed areas.
RO Pressure Tank Injection Mold
Custom injection mold for reverse osmosis pressure tank components, supporting high-pressure water storage product development.
Overview
RO pressure tanks store filtered water under pressure for on-demand delivery. The plastic shell must withstand repeated pressure cycles while maintaining structural integrity and preventing leakage at connection points.
Shengqi reviews the tank design including shell wall thickness, dome structure, thread interface, bladder connection and air valve port before mold design.
For pressure-bearing products, material selection, weld line positioning and structural reinforcement are critical engineering considerations that affect both mold design and production quality.
Engineering Focus Areas
Thread and Connection Design
Water connection threads, air valve ports and bladder sealing interfaces require precise mold features. Unscrewing mechanisms or thread inserts may be needed.
Material and Process Stability
Reinforced PP materials require specific processing conditions. Mold wear resistance, venting and cooling design affect long-term production stability.
Quality Testing Integration
The mold should support consistent production of parts that pass pressure testing, leak testing and dimensional inspection. Process parameter windows are established during trial molding.
