JONWAI – PM Series
Turnkey Production System
- Resin dryer
- Dehumidifier
- Chiller
- Mold Sweat Protector
- Back end automation
Clamping Unit
Enlarged ejector system and longer ejector stroke is especially designed to match the ejector requirement of PET preform.
The external five points double toggle system and strong platens design can distribute the clamping force evenly to the mold. Sensitive mold protection device well-prevents damage to molding surface components.
Quality mold manufacturer
- Simultaneous valve gate for high speed open and close motion.
- Waste reduced for cost saving
- Low Acetaldehyde (A.A) level
- All inserts are interchangeable
- Individually temperature controlled nozzles
Quality automation supplier
JON WAI provides high precision preform system achieves high productivity by shortening cycle time.
Injection Unit
Two-stage injection unit consists of one screw for pre-plasticizing and one plunger for injection.
LOW A.A levels and high torque force with outstanding melt quality are ensured by the injection unit of L/D ratio 1:25 performance screw.
Independent injection cylinder provides wider range of shot size. Without the use of check-ring, it can avoid unstable injection, and increase motion precision.

CORE FEATURES
Low A.A levels and very high throughout with outstanding melt quality are ensured by PM-series.
PM-series provide the high performance of the injection unit and precise for high productivity with help of the robotic handling system to reduce the cycle time.
Aside from the injection machine, the Preform system is a turnkey production system including mold, robotic handling system, granule drying system, recirculating air conditioning for the mold, and refrigeration system.
Preform System Advantages
- Low acetaldehyde (A.A) levels for best perform quality.
- Fast and precise for high productivity.
- Compact to save space for your down stream equipment.
- Custom fit to meet your production needs.
Preform System Characteristics
Injection Unit
Two-stage injection unit consists of one screw for pre-plasticizing and one plunger for injection.
LOW A.A levels and very high trough put with outstanding melt quality are ensured by the injection unit’s 25 D high- performance screw.
The separate shooting pot can get a wider range of shot size. Without the use of check-ring, It can escape the unstable injection and increase the precision of shooting.
Clamping Unit
Enlarged ejector system and longer ejector stroke is especially designed to match the ejector requirement of PET preform.
The external five points double toggle system and thick platens design can distribute the clamping force evently to the mold. With the sensitive mold protection device, it well prevent damage to molding surface components.
