Pipe Fitting Mold for PVC Tee Consistency
Built to hold branch dimensions, cleaner sealing surfaces and faster startup approval.
Buyer concern
The tee needed all three branches to stay in range while keeping ejector marks away from the sealing area.
DFM decision
JFMOULD optimized the cooling around the junction, improved venting and refined the thread-forming surfaces for easier maintenance.
Trial outcome
T1 approval came with fewer manual sizing corrections before startup.
Engineering Snapshot
What a buyer could verify before moving into RFQ
Water supply systems
718H
8 weeks
From DFM to T1
Manufacturing Process
- DFM review for tee-junction filling, sealing surfaces, and ejection
- Cooling, venting, and thread-forming surface preparation
- Mold fitting, T1 sampling, and engineering correction review
Inspection Plan
Quality Control
- Three-branch dimensional and ovality checks
- Thread and sealing-surface inspection on trial parts
Program Notes and RFQ Context
This case demonstrates how fitting geometry, sealing quality, and maintenance access can be balanced in a production-minded tool.
Buyer-fit snapshot
- Part type: PVC tee fitting used in water supply systems.
- Tooling scope: 2-cavity mold in 718H with a 31-second cycle target.
- Review focus: branch dimensions, thread-forming surfaces, and sealing-area cleanliness.
Engineering decisions that mattered
- Cooling was tightened around the tee junction so all three branches could stay more consistent through sampling.
- Venting was improved to keep the sealing area cleaner and reduce extra manual correction before approval.
- Thread-forming surfaces were refined with maintenance access in mind because this buyer needed a stable startup, not only a good first sample.
Trial outcome the buyer could judge
- T1 moved forward with fewer manual sizing corrections before startup.
- The finished part review stayed focused on branch dimensions and sealing surfaces instead of broad rework.

90 Degree Elbow Mold for Ovality Control
Built to hold ovality, cooling balance and faster line qualification.
- Challenge
- The elbow geometry created uneven cooling around the bend, leading to dimensional drift and ovality risk.
- Result
- Ovality stayed in range and the line moved into serial production with limited tuning.
Union Connector Mold for Thread and Seal Stability
Built to keep thread quality, sealing flatness and maintenance access practical.
- Challenge
- Thread quality and sealing face flatness had to remain stable while the customer pushed for lower molding cost.
- Result
- Customer trials assembled smoothly and shorter cycles helped hit the cost target.
Pipe Fitting Ball Valve Body Mold
Valve body mold developed for pressure-sensitive geometry, core stability and consistent downstream assembly.
- Challenge
- The valve body required pressure-sensitive sealing geometry and dimensional control around the rotating core area.
- Result
- The customer achieved stable assembly torque and reduced rework on the downstream valve line.
