High Pressure Ram Extruder & Preformer (Precision Rubber Slicer), JYZH Series

Rubber processing machine with high extrusion pressure for rubber blanks & preforms production

The high-pressure precision ram extruder and preformer machine in the JYZH series has a maximum operating pressure of 40 MPa. It is capable of efficiently straining rubber materials of various hardness levels and performing cutting and acceleration processes on the strained materials with a precision of up to 300 mesh, all without unexpected vulcanization.

This series of ram extruder and preformer is equipped with a standard hydraulic switch door, making it easy to open the head with just one press. It's highly efficient and precise, perfect for producing rubber blanks.

The high-pressure precision extruder and preformer is ideal in producing rubber blanks with its capability to fine-tune and cater to a variety of shapes and materials, including annular, rectangular, strip-shaped and special-shaped rubber blanks. From sealing components, granules, inflation valves, bottle stoppers, tennis balls, oil seals, shoe soles to auto shock absorbers, the machinery yields high precision and efficiency in its production. Its great versatility is further boosted by its integrated process such as vacuuming, straining, extruding, cutting, weighing and counting.

Advantages Maximum pressure up to 40 Mpa, allowing for a quicker extrusion. This speeds up the process of cutting and straining, and helps to reduce the risk of secondary pollution.
Thanks to PLC control with touch screen, the rubber ram preformer allows operator to input parameters with ease.
Quick product set-up of up to 1000 different products database and access them as needed.
Variable frequency motor controls enable stepless, precise speed changes of the cutter, guaranteeing the weight accuracy of rubber blanks.
Using a scales feedback system to ensure automatic adjustment of weight, and set the speed of the cutter accordingly Reliable safety is guaranteed via interlocking devices to secure the head closing, cutter rotation, and ram movement (forward and backward). Prompt and error message: e.g. empty tank, net cover unsecured.
The ram can be separated from the barrel for the purpose of conveniently cleaning residual rubber inside the ram and the barrel.
A vacuum system to effectively clear leftover air in the rubber blank.
Stainless steel coated conveyor with net cover, preventing the accumulation of any unwanted particles.
Premium customization available, including open barrel, retractable conveyor and fixed-length cutting system and more. Details
