Production line and factory setup overview
Designs and manufactures injection moulds for PP-R, PVC, PE and similar pipe fittings such as elbows, tees, couplers and valves through resin and standard review, core/cavity machining, slider and unscrewing design where needed, cooling/ejection fitting, injection trials, pressure-fit samples and cycle validation.
Recommended lowest-entry line configuration Start with two or three standard fittings for one resin and one machine platform. Confirm pipe standard, outside diameter, wall thickness, thread or socket detail, shrinkage, cavity count, clamp force, shot size, cooling, ejection and leak/fit acceptance before cutting steel.
Production process and implementation sequence
- Target-machine and buyer-drawing review
- CAD/CAM and material/heat-treatment selection
- Cutting, machining, EDM or CNC routing
- Assembly, fitting and surface finishing
- Trial production with target material
- Measurement, functional checks and repeat-cycle inspection
- Packing, documentation and release
Products, capacity and market fit
- Tooling must be designed around the target production machine and released buyer drawing.
- First-off samples, measured dimensions and repeat-cycle evidence must be accepted before production release.
- Start with one high-demand product family and retain tool drawings, settings and maintenance records.
- Pipe-fitting injection moulds - Named injection machine, resin and pipe standard; fitting size, socket/thread detail, cavity count, cooling/ejection, dimensional and pressure-fit requirements - Pipe and fitting factories, plumbing distributors, building-material suppliers and repair-tool buyers
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
| Fitting DFM/CAD station | Matches fitting, resin and machine | Standard and shrinkage |
| CNC/EDM core-cavity cell | Machines socket/thread geometry | Dimensional tolerance |

| Cooling/ejection station | Completes functional circuits | Cycle and demoulding |
| Injection and fit trial | Checks moulded fitting | Socket/thread/leak fit |
Raw materials, utilities and factory requirements
- P20/718/H13 steel as specified, mould bases, sliders, ejectors, cooling fittings, guides, springs, polishing consumables, gauges and target resin
- Stable three-phase power, guarded machining, calibrated measuring tools, covered material/tool storage and safe lifting/handling
- Documented maintenance, critical wear spares, approved coolants/lubricants and product-specific safety controls
Indicative low-entry investment and implementation plan
These planning ranges prioritize economical machinery, local labor and local civil works. Final pricing follows confirmed capacity, product specification, delivery terms and site conditions.
| Scope | Indicative range | Entry-plan note |
|---|---|---|
| CAD/CAM, CNC/EDM and mould-base tooling | US$55k-200k | One fitting family |
| Sliders, cooling, assembly and gauges | US$25k-100k | Size and cavity dependent |
| Injection trials and first wear spares | US$15k-65k | Standard/resin validation |
| Indicative entry total | US$95k-365k | Injection presses and pipe test laboratory excluded |
