Why Global B2B Buyers Choose Our Equipment
Zero-Degradation Thermal Control (+/- 0.5°C): Independent multi-zone PID barrel cooling fans and heating bands strictly prevent PVC resin overheating, eliminating HCl gas degradation, yellowing, and black spots.
Corrosion-Proof Chrome-Alloy Flite: Specially nitrided bimetallic screw and barrel with high-chrome plating withstand continuous acid release from PVC compounds, extending component lifespan by up to 40%.
High-Speed Multi-Cavity Balance: Engineered for 4-to-16 cavity cup molds with dynamic injection pressure curve compensation, ensuring less than or equal to 1% weight deviation across all cavities during 12-to-28s cycles.
Air-Cooling Barrel Layout: Built-in high-volume forced air cooling jackets on each heating zone quickly pull heat away from the barrel, resolving the intrinsic shear-heating problems of rigid PVC compounds.
Engineering Excellence & Quality Control
Factory Verification Standard: Every PVC machine undergoes a strict 48-hour continuous simulated load test and a 100-shot operational trial utilizing rigid PVC compound to check barrel thermal equilibrium before shipping approval.
Hardened Anti-Corrosive Nozzle: Extended, wide-flow nozzle design eliminates dead corners where PVC melt could stagnate, burn, and contaminate subsequent production batches.
Parallel Tie-Bar Precision: Clamping unit alignment deviation is maintained under 0.05mm, preventing localized mold flashing and ensuring uniform rim sealing on stackable cups.
Proportional Closed-Loop Hydraulics: Fast-response servo valves deliver stable holding pressure curves, eliminating short-shots at thin-wall bottom gates.
Automation & Production Line Integration
Downstream Ready: Built-in Euromap 67 robotic interface supports high-speed top-entry side robots for automated cup extraction, nesting, and stacking.
Turnkey Capability: Natively syncs with automated inline cup counters, plastic bagging systems, and In-Mold Labeling (IML) stations.

FAQ
Q: How does this machine solve the issue of PVC burning and yellowing inside the barrel?
A: We use a specialized low-shear, low-compression screw profile paired with active air-cooling fans on each barrel zone. This keeps the melt temperature under the critical degradation threshold (+/- 0.5°C control), preventing friction-induced overheating.
Q: What specific material upgrades are applied to resist PVC's corrosive chemical properties?
A: The entire screw, barrel, and nozzle tip assembly are made from premium bimetallic alloys treated with high-temperature nitriding and dense chrome plating. This shields the core steel from corrosive hydrochloric acid (HCl) vapors released during PVC plasticization.
Q: Can this machine run both transparent rigid PVC and colored modified PVC compounds?
A: Yes. The control system features dedicated material processing recipe presets. The screw geometry provides enough mixing torque to disperse color masterbatches evenly without shearing transparent PVC into a hazy texture.
Q: What is the typical mold maintenance lifespan when running a 16-cavity thin-wall cup mold on this unit?
A: With our high-rigidity platen design and strict parallelism control (less than or equal to 0.05mm deflection), mold clamping force is distributed perfectly. This reduces tool edge wear, extending premium tool life up to 1,000,000 cycles under proper lubrication.
Q: Can I run recycled PVC scrap or regrind through this injection system?
A: Yes, up to a specific percentage depending on your structural requirements. For regrind materials, we recommend our optional bimetallic screw package with an enlarged, self-cleaning nozzle filter to capture any foreign contaminants without causing melt stagnation.
Q: What is your standard lead time for a complete automated cup production line?
A: A standard PVC injection molding machine requires 25–40 working days. If your procurement order includes custom high-speed multi-cavity molds and robotic takeoff-stacking automation, the entire validated line requires 50–70 working days.
Q: Which international component brands are integrated to ensure global spare part availability?
A: We utilize Tier-1 global industrial brands: KEBA/Techmation controllers, Vickers/Yuken proportional hydraulic valves, Schneider electrical switchgear, and Phase/Sumitomo energy-saving servo drive systems.
