Cosmos Integrity Engineering successfully finished Factory Acceptance Testing for the SWT-PH5000 sheet butt fusion welding machine at MM-Tech. This big step proves the machine is ready for tough plastic manufacturing projects. Tests showed full agreement with DVS 2207 standards while using high-quality YUHAN PVC-U sheets. Break tests proved that the weld was even stronger than the original material.

Key Takeaways

The SWT-PH5000 welding machine passed tough tests and made plastic welds that were stronger than the base material.
Smart computer systems control the heat and liquid pressure to keep the material safe during the welding process.
This high-tech machine helps companies make top-quality industrial plastic tanks with strong, leak-proof joints.

Successful FAT for Sheet Butt Fusion Welding Machine

The engineering team finished strict Factory Acceptance Testing for the SWT-PH5000 unit at MM-Tech. Cosmos Integrity Engineering guided all trial runs to check total machine accuracy. Technical experts checked each main feature under actual working conditions inside the factory. This success confirms that the heavy equipment is fully ready for tough industrial plastic fabrication projects.

Compliance with DVS 2207 Standards

Technicians ran all welding steps to follow the set DVS 2207 standard closely. This famous international rule gives exact heat levels and force numbers to join industrial thermoplastic materials safely. The engineering team set ideal heat levels and pressure timing during testing on thick plastic sheets. Exact digital controls kept correct heat limits during each heating step. Automated hydraulic power adjusted physical force correctly during the first bead building stage.

Benchmark	Recorded Value / Result
Machine tested	SWT-PH5000 sheet butt fusion welding machine
Material	PVC-U sheets, 10 mm and 20 mm thickness
Standard followed	DVS 2207
Welding temperature (20 mm sheet)	215°C
Beading time	100 seconds at 1000 N/mm² pressure
Soaking time	20 seconds
Cooling time	3000 seconds, optimized for ambient site temperature
Destructive test result	Weld joint tensile strength exceeded base material strength

The collected technical numbers show full agreement with strict international quality rules. The sheet butt fusion welding machine kept steady heat contact across the whole heater plate without damaging any material. Regular sensor tracking showed exact force movement and even pressure distribution across the whole fusion line during every test run.

Material Compatibility and Destructive Tensile Tests

Engineers checked overall material quality using top YUHAN ALFA-SIM PVC-U sheet products from South Korea. The full material compatibility tests used two specific sheet thicknesses, including 10mm and 20mm thermoplastic panels. Technical staff noted easy heat intake and steady thermal action across both panel sizes. The even heat spread across the heating plate surface stopped material burning and effectively removed inner heat stress inside the joined seam.

After finishing the fusion step, quality control technicians did tough destructive tensile tests on the welded plastic pieces. Special lab equipment pulled hard directly across the joined seam area. The strong weld joint showed great mechanical strength under heavy pulling force. The test piece finally broke inside the main sheet body instead of along the welded seam line. This breaking test proved that the joint strength was higher than the original strength of the base PVC-U sheet itself. The successful result promises great mechanical performance for long-term heavy-duty industrial jobs.

Technical Features of SWT-PH5000 Welding Unit

Precision Heating and Pressure Control

The SWT-PH5000 sheet butt fusion welding machine uses electronic temperature controls on a premium aluminum plate. This smart system keeps surface heat changes within a small ±3°C (±5.4°F) range. ASTM F2620 rules require a plate heat between 400–450°F (204–232°C) to stop cold spots in plastic joints. Digital sensors check heat shifts constantly to protect raw plastic materials from heat damage.

> Butt fusion welding machines allow accurate control of pressure, time, and temperature.

The hydraulic drive delivers exact force during every step of the welding process. Workers use a contact pressure of 60 psi to 90 psi for normal plastic materials. An extra hydraulic tank balances out sheet shrinking while the plastic cools down. Built-in pressure safety valves shield hydraulic hoses from sudden pressure spikes.

Impact on MM-Tech Manufacturing Capabilities

Optimizing Industrial Plastic Tank Fabrication

Factory Acceptance Testing verifies overall system performance before factory delivery. The trial process identifies potential leaks or structural weak points long before site installation. Documented test results support full traceability, troubleshooting, and continuous operational quality improvement. Highly reliable machinery directly strengthens daily operations across chemical processing, electroplating, firefighting, and environmental protection sectors. Quality testing builds total customer confidence across demanding industrial projects.

The equipment processes PE, PP, PVC, and PVDF sheets from 2 mm to 50 mm thick and up to 4 m wide. Built-in automated temperature control within ±5°C minimizes weld bead defects and material misalignment. Tank structural calculations and welding procedures follow DVS 2205, DVS 2207, and DVS 2208 engineering standards. Quality control technicians verify finished liquid storage containers through a complete 24-hour hydrostatic water test at maximum operating volume. Fusion seams routinely achieve 90–95% weld strength relative to parent material alongside a precise ±0.5 mm dimensional tolerance.

Integration with Comprehensive Thermoplastic Equipment

The SWT-PH5000 sheet butt fusion welding machine serves as the primary operational anchor inside the manufacturing line. This machine produces strong, seamless sheet joints for heavy industrial panel assemblies. Fabrication teams connect this machine directly with the SWT-ZW4000 sheet bending welding machine. This combination shapes flat panels into smooth cylindrical tank bodies without creating internal material stresses.

MM-Tech integrates multiple specialized tools into one synchronized production workflow:

The SWT-YF1530 CNC engraving machine performs exact cutting and edge preparation on panel parts before final assembly.
The SWT-NS600A extrusion welder applies heavy-duty structural welds on thick load-bearing joints.
The SWT-NS1600S hot air gun completes detail welding operations and seals delicate pipe fittings.

Cosmos Integrity Engineering successfully completed Factory Acceptance Testing for the SWT-PH5000 sheet butt fusion welding machine at MM-Tech. This key achievement highlights MM-Tech’s firm dedication to continuous innovation, rigorous quality testing, and proven thermoplastic solutions. Precise engineering parameters consistently deliver maximum weld joint strength and guarantee long term operational integrity across demanding industrial manufacturing applications.

FAQ

What standard guided the SWT-PH5000 factory acceptance testing?

Engineers used the DVS 2207 standard while running these trials. This international guideline sets exact heating temperatures, push forces, and timing rules to join industrial plastic sheets safely.

Which welding parameters applied to the 20mm PVC-U sheets?

Technicians kept heat levels at 215°C for this process. The machine used 1000 N/mm² force for 100 seconds to build beads, then soaked for 20 seconds and cooled for 3000 seconds.

How did the welded joints perform during destructive testing?

Hard stress tests pulled on joined plastic parts until they snapped. The welded seam turned out stronger than the plain PVC-U sheet itself, so the test piece broke away from the joint line.
