High Pressure type Rubber Preforming Machine

Machine head,barrel use special material through tempering treatment.

Product Details

Quick Details


This rubber preforming machine  is High Pressure type compared with the standard Preformer machine,it is a high efficiency machine to produce high precision rubber blanks.The max.extrusion pressure for the High-Pressure Precison Preformer is up to 5500 PSI,with wide application,especially for kinds of rubber with high hardness and poor fluidity,like viton,achieving rubber filtering(screening) and cutting simultaneously.Filtering level can reach 300 mesh,can cut different shapes of rubber blanks

by installing relevant dies.

It combines the functions of vacuum system,filtering(screening),extrusion,cut,weighing,calculation.

The machine is user-friendly design,easy operation and maintenance.

Adopt PLC control and touch screen operation. Color display guide you to easily perform data entry, password protection.

It can store 1000 kinds of products data,which can be used any time.

Variable frequency motor control the cutter speed infinitely.

Electronic scale is with closed-loop feedback,automatically to control weight of rubber blank.

Reliable security, the movements of head ,cutter and plunger piston are interlocking. 

Failure will be shown by icon and text.

Vacuum system: before extruding and cutting, using vacuum system to remove the air and gas in barrel, head, inside the compound mixture, thereby enhancing the quality of products under the curing process. 

Heating System: The water cycle heating mode, temperature control by a digital thermostat and display. Ensure nose, barrel temperature constant. 

Single cylinder design ,barrel is lengthened,improving mechanical stability,easier to clean.

Machine head,barrel use special material through tempering treatment.

Machine head close/open is by hydraulic control,for safety purpose,operator need to use 2 hands to push buttons when closing the head.

Piston head is newly optimized structure,there will be less rubber leftover after cutting finishes,and easy to take out the leftover.

Die assembly:1set. Filtering (screening) assembly:1set. Dies:8 PCS.
