Precision Rubber Preformer, EBQ250 Series
Rubber ram preformer for the preparation of rubber blanks for shoe soles and under sleeper pads
The EBQ250 series precision rubber preformer is tailored for the production of flat and elongated rubber products such as rubber sole blanks and under sleeper pads of up to 300 mm. This model stands out from other general purpose precision preforming machines offered by Deren, as it boasts a different Shoe Sole head. Its great versatility is further boosted by its integrated process such as vacuuming, straining, extruding, cutting, weighing and counting.

- 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.
-
- Automatic Hydraulic Door Switch
In comparison to manual door opening and closing, hydraulic-driven door control is simpler, more secure, economical, and efficient.
-
- Scrap Reduction Device
The installation of a scrap reduction device on the machine head can significantly increase the efficiency of rubber material utilization. However, the taper structure of the head can cause the rubber material to be subjected to uneven pressure, resulting in a larger weight accuracy deviation than the standard ram head.
-
- Stainless Steel Wrapped Rack Panel
The paint that is usually used can chip off, potentially leading to contamination of the product. By using a stainless steel wrap, this issue can be avoided and any contamination can be prevented.

-
- Full Screen Touch Control
Use a full screen touch screen to adjust and preset parameters including operation modes and oil temperature, simplifying operation and providing a more intuitive experience.
-
- Servo Cutting System
Speed ranging from 0.5 to 400 revolutions per minute (rpm) and instantaneous cutting speed from 50 to 150 rpm. It is ideal for cutting large or long items to avoid clogging.
-
- Cut-to-Length System
Cut-to-length system combines light sensing with cutter to control the length of the rubber strips. This technique is largely utilized for the purpose of filtration and cutting of silica gel mixed rubber, which is further used in injection machines.
-
- Open Barrel
The rear-end of the device is designed for feeding, so the ram head doesn't need to be opened. No residual materials in the ram head need to be taken out either, resulting in a lower labor intensity and increased production efficiency, perfect for mass production.
-
- Retractable Conveyor
At the beginning, the weight of the rubber blanks will vary. When the desired accuracy has been achieved, press the button to start the conveyor and utilize the touch screen to accurately distinguish between qualified and non-qualifying rubber blanks by counts.
-
- Barcode Scanner
A barcode is scanned in the production process, allowing for an instantaneous retrieval of process parameters. This visualization of the task eliminates potential for errors resulting from manual input of data by workers.
-
- Data Interface
In order to achieve modern management, ERP and other management systems can be connected to the rubber ram preformer with the aid of data interfaces like RS232.
-
- Displacement Sensor
The position of the start and end points of the ram can be set on the touch screen based on production capacity required; this results in increased efficiency as well as a more visible display of residual material in the loading barrel.
