A UPVC profile extrusion line may look complete yet arrive with unstable output, weak cooling, wiring errors, drifting dimensions, rough cuts, or missing documents. A factory acceptance test, or FAT, is the last point to find these problems before the machine ships from China.
A useful UPVC profile extrusion line FAT checklist tests the full production route, records measurements, and links each failure to a correction and retest. These 12 checks cover the extruder, calibration table, haul-off, cutter, stacker, controls, safety, profile quality, and shipment package.
Agree on the FAT protocol. State the drawing, PVC formula, mould, target output, cutting length, voltage, utilities, and duration. Pass limits must come from the contract and approved samples.
Record | What to capture | Pass point |
Equipment list | Main units, accessories, identification | Matches the order |
Test material | Formula, batch and condition | Matches the trial |
Measurements | Dimensions, weight, speed and output | Within approved limits |
FAT report | Photos, video, faults and retests | Signed and complete |
Keep the line accessible. During remote FAT, show the control screen, measuring tools, material feed, cutter, machine plates, and samples.
Anda’s UPVC Door and Window Profile Making Machine links a conical twin-screw extruder with vacuum calibration, haul-off, cutting, and stacking. The same preparation applies to a WPC Decking Production Line, where mixing, feeding, forming, cooling, finishing, and handling work as one process.
These checks confirm that the UPVC profile extrusion machine matches the approved order and can run safely before hot material enters the screw.
Compare the line with the approved layout and component list. Check machine direction, table length, utility connections, feeding route, cutter, stacker, electrical supply, and maintenance access. Record unit identification.
Look for frame distortion, unfinished welds, oil leaks, loose guards, sharp edges, weak cable support, or misaligned rails. Covers, clamps, doors, and adjustment points should move correctly.
Check cable labels, terminal tightness, grounding, ventilation, overload protection, and separation of power and signal wiring. Verify that voltage and frequency match the destination factory. Electrical drawings should match the installed cabinet.
Run manual and automatic functions. Check heaters, motors, pumps, haul-off, cutter, and stacker. Test alarms for over-temperature, overload, emergency stop, low water flow, and guard opening. The line must stop safely and require a restart.
Anda’s UPVC Door and Window Profile Making Machine produces window and door profiles with matching moulds and settings. A WPC Decking Production Line needs separate tooling, formula, cooling setup, and FAT records because wood-plastic material behaves differently from rigid PVC.
A demonstration is not a production test. The line should reach stable conditions, hold them, and produce traceable samples from the agreed material.
Operate motors, pumps, fans, haul-off tracks, cutter, and stacker without material. Listen for vibration, rubbing, leakage, or pump cavitation. Confirm rotation direction and current draw.
Feed the specified compound and record warm-up time, zone settings, screw speed, motor load, line speed, output weight, and startup scrap. Calculate output from weighed profiles over a recorded period.
Take samples at fixed intervals. Measure critical width, wall thickness, chamber geometry, straightness, weight per meter, and cut length. Check for waves, die lines, burn marks, bubbles, pits, color streaks, glossy patches, and collapsed ribs.
Check vacuum, water flow, table alignment, and haul-off speed. Uneven vacuum causes size drift; weak cooling lets profiles bend; excessive pull thins walls. Change speed, then confirm dimensions return to range.
Anda’s UPVC Door and Window Profile Making Machine coordinates extrusion, vacuum forming, traction, cutting, and collection. A WPC Decking Production Line FAT should add moisture checks, hollow-rib inspection, surface review, and synchronization of embossing, sanding, brushing, or co-extrusion equipment.
These tests confirm final shipment readiness.
Program multiple cut lengths and measure pieces. Check squareness, edge cleanliness, dust extraction, repeatability, and cutter tracking. The stacker should receive profiles without scratching or twisting.
Test every emergency stop, guard switch, grounding point, alarm, and barrier. Hazardous motion should stop as designed. Hot surfaces, rotating shafts, saw areas, and electrical zones need labels and physical protection.
Hold the agreed production condition for a defined period and log readings. Then make a controlled stop and restart. Watch for PVC degradation, color change, vacuum loss, cutter errors, or dimensional drift after production resumes.
The release package includes:
· Signed FAT results with readings and sample numbers
· Electrical, layout, foundation, and utility drawings
· Operation, maintenance, cleaning, and troubleshooting instructions
· Spare-parts and tooling lists
· Packing photos, accessory counts, labels, and rust protection
Failed items need an owner, correction date, and retest proof. Technical faults should not be postponed to the site acceptance test.
Anda can supply the UPVC Door and Window Profile Making Machine with installation, commissioning, and training support. When a WPC Decking Production Line includes mixers, auxiliary extruders, finishing, or recycling equipment, each ordered unit should appear in FAT and packing records.
Zhangjiagang Anda Machinery Co., Ltd. manufactures extrusion equipment for UPVC profiles, pipes, panels, and WPC products. Services cover planning, installation, commissioning, and training.
For a UPVC Door and Window Profile Making Machine, the extruder, mould, calibration, haul-off, cutter, and stacker must match the buyer’s drawing and output target. Welcome to watch Anda’s UPVC Door and Window Profile Making Machine video before arranging a FAT.
Alongside the UPVC Door and Window Profile Making Machine, Anda’s WPC Decking Production Line covers mixing, feeding, extrusion, forming, haul-off, cutting, stacking, and optional treatment for hollow outdoor decking profiles.
A UPVC profile extrusion line FAT checklist should create evidence, not impressions. Verify configuration, build, electrical work, controls, dry operation, material output, profile measurements, cooling balance, cutting, safety, endurance, documents, and packing. Set pass limits before testing and hold shipment until faults are corrected and retested.
A properly tested UPVC Door and Window Profile Making Machine is easier to install and bring into stable production. The same discipline reduces risk when purchasing a WPC Decking Production Line with extra mixing, co-extrusion, finishing, or recycling equipment.
The answers below address common questions raised during machine pre-shipment inspection and supplier evaluation.
It is a documented inspection and production trial completed at the supplier’s factory before shipment. It checks whether the machine matches the order, operates safely, produces the agreed profile, and includes required documents and accessories.
There is no universal duration. The contract should allow time for temperature, output, vacuum, cooling, haul-off speed, dimensions, and cutting to stabilize. The test should also include a stop and restart.
Record critical widths, wall thicknesses, chamber dimensions, straightness, weight per meter, surface condition, and cut length. Number each sample and note its time, line speed, and settings.
Video supports remote witnessing, but it should show live readings, measurements, machine identification, and retest evidence. Edited clips cannot prove that the ordered line passed every item.
The core checks are similar, but WPC needs extra controls for wood-powder moisture, mixing, hollow-board cooling, surface defects, finishing, and dust collection. Buyers comparing it with an UPVC Door and Window Profile Making Machine should use separate material-specific acceptance limits.
