When manufacturing high-performance PTFE (polytetrafluoroethylene) components whether rods, tubes, rings, or custom geometries uniform compression across the entire mould cavity is critical to achieving consistent mechanical properties. The SuKo Double-Action Semi-Automatic Molding Machine delivers precisely that through its synchronized upper and lower hydraulic cylinder system.
PTFE’s remarkable chemical resistance, near-zero friction coefficient, and broad thermal range from -200C to +260C make it the material of choice for aggressive chemical environments, high-precision electrical insulation, and biocompatible medical implants. However, PTFE’s unique rheological properties also make it challenging to mold: without uniform pressure distribution during compaction, the resulting part will exhibit density variations that degrade mechanical strength and compromise dimensional accuracy.
The SuKo dual-cylinder system applies synchronized pressure from both above and below the mould simultaneously, ensuring complete and uniform compaction of PTFE material throughout the cross-section of the part. This bi-directional compression eliminates the central porosity and density gradients characteristic of single-cylinder presses, producing PTFE components with consistent mechanical properties batch after batch.
Machine Overview
This machine is engineered for pure and modified PTFE grades and produces a wide variety of industrial molded parts including rods, tubes, rings, custom geometries, and large-area seals. The semi-automatic operating mode strikes an effective balance between production throughput and process flexibility, making it suitable for both high-volume production runs and smaller batches with frequent product changeovers. Alongside this press, SuKo Machine manufactures complementary equipment including the PTFE Corrugated MachinePTFE Corrugated Machine for corrugated tubing and the PTFE Hose Paste ExtruderPTFE Hose Paste Extruder for high-precision tube extrusion. SuKo Machine also offers the PTFE Sintering FurnacePTFE Sintering Furnace for post-molding sintering, and the Polymer Molding MachinePolymer Molding Machine for rods and profiles, providing complete turnkey production lines from raw PTFE material to finished part.
Designed for pure and modified PTFE, this machine produces a wide spectrum of industrial molded parts. Its semi-automatic operation model makes it equally suited to high-volume production runs and smaller batches with frequent product changeovers. SuKo Machine also manufactures complementary equipment including the PTFE Corrugated MachinePTFE Corrugated Machine for corrugated tubing and the PTFE Hose Paste ExtruderPTFE Hose Paste Extruder for high-precision tube extrusion.

as a complementary piece of equipment, allowing customers to procure a complete molding and sintering solution from a single manufacturer.
FAQ
Q: What is the maximum part diameter this machine can produce?
A: The machine accommodates outside diameters up to 2000mm+, covering the majority of standard PTFE molded part sizes.
Q: Does the machine handle filled or modified PTFE grades?
A: Yes. The 20MPa maximum pressure accommodates pure PTFE and all standard filled or modified PTFE compounds.
Q: What kind of after-sales support is available?
A: We provide remote technical support, on-site installation guidance, and operator training. Spare parts are stocked for express shipment.
Q: Is the touch screen interface available in other languages?
A: Currently Chinese and English are standard. Additional languages can be configured for specific orders.
Q: What is the typical delivery lead time?
A: Standard configurations ship within 30-45 days of order confirmation. Customized machines require 45-60 days depending on specification complexity. Installation and commissioning support is available worldwide.
Q: Does the machine require special foundation or utilities?
A: The machine requires a standard industrial three-phase power supply (380V 50Hz 3P) and level concrete foundation. Compressed air supply (0.4-0.6MPa) is needed for pneumatic components. No special cooling water system is required for standard configurations.
