Hot Feed Rubber Precision Preformer, DRLW-Q Series
Rubber preforming machine combining screw extruder and gear pump for making rubber blanks
The hot feed rubber precision preformer is a highly efficient and accurate machine used for producing rubber blanks. The preformer operates by conveying hot rubber material using a screw and gear pump and cutting it into fixed sizes and shapes. It can be used for producing a wide range of rubber and silica gel products, and its precision, compact size, and ease of operation make it an ideal choice for independent production processes. Additionally, the hot feed rubber preformer is capable of producing rubber blanks in various shapes including rings, strips, and rounds, making it suitable for the manufacturing of rubber miscellaneous parts, sealing parts, oil seals, inflating valves, tennis balls, soles, and other rubber products.

Advantages
- The hot feed rubber precision preformer is utilized to cut the normal temperature strip rubber compound into the customer's desired shape and weight continuously. The weight accuracy of the rubber blank is monitored to within ± 0.5% via the control of a gear pump.
- Using a scales feedback system to ensure automatic caliberate of blank weight.
- Error alarm with an icon displaying fault location, acting as regular reminders for workers to conduct spot-checks and calibrate the weight of rubber blanks.
- Reliable systems and interlock head and cutter can help prevent work-related injuries.
- Stainless steel sealing of all machine heads prevents rubber from spilling onto the ground, resulting in decreased pollution, as well as conserving the raw material.
- Quick product setup with PLC control and process parameters database.
- A separation structure using an electric motor supports the gear pump, screw and machine head, simplifying rubber raw material replacement and conducting easier cleaning.
- The searchlight is a useful tool for cleaning, helping to ensure that all those tricky, hard to reach spots don't get overlooked.
- Both system and extrusion pressures are intuitively displayed on the touch screen.
- When creating a prototype of a new product, having a PLC in operation provides useful data that can be used to streamline the process.
