FRP fan housing forming hydraulic press_2000 ton frame hydraulic press

The FRP fan housing and blades in the FRP negative pressure fan are made of SMC materials. SMC sheets are used in combination with molds and are molded at high temperature and high pressure. The SMC compression molding process is more suitable for rapid batch production. It has good molding effects, low production costs, and high precision. It is currently a processing method with a relatively high degree of recognition. The hydraulic press for molding the FRP fan housing is commonly used in 1200 tons, 1500 tons, 2000 tons, 2500 tons, etc. according to the specifications of the FRP fan housing. The hydraulic press for molding FRP fan blades is mostly 315 tons, 400 tons, 500 tons, etc., and can be customized with four-column or frame structures according to customer requirements and process design.

2000 ton FRP fan housing molding hydraulic press is mainly used for the molding and pressing process of SMC BMC sheet molding compounds, meeting all the requirements of the pressing process. The equipment temperature, curing time, pressure and speed are in line with the process characteristics of SMC/BMC materials; it adopts PLC control, easy to operate and adjustable working parameters; this equipment can be optionally equipped with an in-mold core pulling control system and a preset in-mold ejection control system, which can realize a series of actions such as fast descending, segmentation and pressing, segmented deflation, working, pressure holding, slow mold opening, fast return, slow demolding, fast ejection, ejection stop, fast return, etc., and the temperature can be controlled at multiple points.

SMC Sheet

After replacing the mold, the FRP fan housing molding hydraulic press can also be used to mold FRP septic tanks and other FRP products. It is a representative of composite material molding hydraulic presses. The work surface, stroke, and opening are customized according to actual production needs. The working pressure, stroke, pressing speed, and slow return speed of this machine can be adjusted within the specified parameter range according to process needs. This machine has an independent power mechanism and electrical system, and adopts button centralized control, which can realize manual and semi-automatic operation modes. This machine is sensitive and simple to operate, has low noise, stable pressure, and can meet the needs of different production processes.

SMC FRP fan housing processing process:

1) Prepare raw materials (resin, glass cloth, gel coat, curing agent, accelerator);

2) The main production process is:

a. Mold preparation: find the corresponding model of SMC FRP fan cover mold, install the mold on the SMC FRP fan cover hydraulic press (315 tons, 630 tons, 1200T, 1800 tons), and heat the mold for standby use;

b. Prepare SMC sheets: cut the SMC sheets into load-bearing slices for standby use;

c. Processing SMC FRP fan casing: When the mold is heated to the specified temperature, all the weighed SMC sheets are placed into the SMC FRP fan casing mold for heating, melting and curing. After the specified time is reached, the mold is raised and the semi-finished FRP fan casing is taken out;

d. Deburring: Remove excess burrs to prevent accidental injuries during transportation.

3) After the finished products are formed, they are put into storage and wait for shipment.
