The SUNTECHMACH SHG315 is the entry model of our HDPE fitting fabrication machine range and the one we ship most often. It fabricates PE, PP and PVDF fittings from 90mm to 315mm — 0-90° elbows, equal tees, equal crosses and 45°/60° Y-pieces — in a workshop instead of buying them in. Total connected load is only 8.15 KW, so it runs on an ordinary 380V workshop supply without a transformer upgrade, and at 800 kg the whole machine can be moved by forklift and set down wherever the work is, which is why distributors and small fabricators use it as their first fitting machine. Like every SHG model it uses one integrated structure: to fabricate a different fitting you change the special clamps, not the machine. The removable PTFE-coated heating plate is independently controlled from 0 to 300°C with ±5°C surface deviation, the electric pivoting planing tool is protected by a safety limit switch, and a separate two-channel timer records the soaking and cooling phases and alarms when each one ends.

Key Features

• 1. 90-315mm Coverage — Covers the standard small and medium PE/PP/PVDF distribution sizes in one machine.
• 2. Lowest Power in the Range — 8.15 KW total (5.15 KW heating plate + 1.5 KW planer + 1.5 KW hydraulic unit), so a normal workshop supply is enough.
• 3. Forklift-Portable at 800 kg — No foundation needed; move the machine to the job instead of moving the pipe.
• 4. Single-Operator Friendly — Compact control desk with handwheels for clamping and centring, designed for one technician.
• 5. Multi-Angle Fabrication — 0-90° elbows, equal tees, equal crosses and 45°/60° Y-pieces; Y clamps and inserts are optional.
• 6. Removable PTFE-Coated Heating Plate — Imported Teflon coating, independent 0-300°C control, ±5°C surface deviation, pivoting for easy loading.
• 7. Electric Pivoting Planing Tool — Safety limit switch prevents accidental start-up.
• 8. Separate Two-Channel Timer — Records soaking and cooling separately and alarms at the end of each phase.

Operation Guide

• Fix the tee/cross or elbow clamps for the fitting you are making on the machine rack.
• Insert the pipe and fitting ends into the clamps, align them and tighten the clamp bolts; check concentricity before planing.
• Start the electric planing tool and shear both faces until a continuous chip forms on each.
• Set the heating plate temperature and let it stabilise.
• Bring the ends against the heating plate under the calculated pressure and hold for the soaking time on the parameter table.
• Remove the plate, join the ends within the change-over time and apply the fusion pressure.
• Hold the fusion pressure for the cooling time shown on the parameter table; the two-channel timer alarms when the phase ends.
• Release, open the clamps and check the fusion bead on both sides.

Common Faults & Solutions

FAQ

Q: Can this machine fabricate HDPE elbows?

A: Yes. The machine can be configured for fabrication of HDPE elbows at different angles. Please provide the required pipe diameter, SDR and fitting angle for machine selection.

Q: Can it produce HDPE tees?

A: Yes. With the corresponding clamps, the machine can be used for workshop fabrication of HDPE tees. The exact maximum tee size on the 315 model is listed from us for your specific fitting type above.

Q: Can it make Y fittings?

A: Yes. The machine is designed for fabrication of Y-type fittings with the corresponding clamping configuration. Both 45° and 60° Y fittings are supported; the maximum size per angle is confirmed on request for your fitting type and angle.

Q: What is the maximum pipe size on the 315 model?

A: The welding range of the 315 model is 90-315mm. The maximum size that can actually be fabricated depends on the fitting type (elbow, tee, cross or Y) — contact us and we will confirm it for your specific fitting type and angle.

Q: What power supply does the 315mm machine need?

A: 380V, 50/60Hz, three-phase. Total connected load is 8.15kW: 5.15kW heating plate, 1.5kW planing tool and 1.5kW hydraulic unit.

Q: How much does the 315mm machine weigh, and does it need a foundation?

A: 800kg. It does not require a poured foundation and can be repositioned with a forklift, which is unusual at this level of capability.

Q: What is the working pressure?

A: 0-10MPa, with a low starting pressure hydraulic system, a reliable sealing structure and a pressure accumulator.

Q: Does it record welding data?

A: Yes. The control panel includes a built-in printer for welding parameter records and a USB port for data export, so each joint can be documented for the project file.

Q: What welding temperature is used?

A: The heating plate is adjustable from 0 to 300°C with ±5°C surface deviation. The actual heating and cooling times come from the welding parameter table supplied with the machine, based on pipe diameter, SDR and wall thickness.

Q: What information is required to select a machine?

A: Pipe material (PE / PP / PVDF), pipe outside diameter, SDR or wall thickness, fitting type, required angle, power supply, and required production capacity.

Q: Can the clamping configuration be customized?

A: Yes. Customized clamping solutions and OEM branding are available — tell us which fittings you actually sell and we build the clamping set around them.

Q: How is the machine delivered and what about after-sales?

A: Export-grade wooden case. Every machine is assembled, wired and test-run in our Hangzhou factory before shipment — hydraulic pressure test, heating plate temperature check at the set points, and planing tool safety-switch test. 12-month warranty, wearing parts excluded.
