Laboratory small flat vulcanizing machine is also called hot press forming machine. It is mainly used for sample preparation of vulcanised rubber and plastic products, such as: tensile test, impact test, compression test, etc.




Intelligent PLC Touch Programmable Control System
Adopts industrial MCBS color touch HMI with fully editable vulcanization workflows. Operators preset clamping pressure, heating temperature, dwell time and automatic exhaust cycles; the system records full process data for traceability. One-click auto cycle includes low-pressure mold closing, high-pressure holding, timed curing and automatic mold opening, eliminating constant manual supervision. Multi-language interface fits global lab operation demands.
2.Precision Hydraulic Pressure Output & Wide Ton Range
Standard hydraulic tonnage covers 10T, 20T, 30T, 50T, 80T, 100T with fully adjustable pressure output. Heavy-duty thick hydraulic cylinder delivers stable compression without pressure drift during long curing cycles. Built-in pressure gauge provides real-time visual pressure readout, ensuring consistent clamping force for every batch of specimens.
3.Uniform Electric Heating Plates with ±1℃ Accuracy
Upper and lower platens adopt integrated embedded heating tube layout paired with independent temperature sensing probes. Max working temperature reaches 300℃ with temperature uniformity controlled within 1℃ across the entire plate surface. High-hardness quenched steel platens feature ultra-flat finishing (parallelism ≤0.1mm) to prevent uneven thickness of molded samples. Single-layer base design, 2/3 multi-layer stacking platens available on request.
4.Adjustable Automatic Exhaust Function
Programmable auto air release cycles (3–10 times per run) eliminate trapped air inside molds, effectively erasing bubbles, pits and incomplete filling defects on silicone and rubber molded parts. Exhaust frequency and hold interval can be tailored to high-viscosity compounds and intricate mold geometries.
5.Full Safety Enclosure & Multi-Level Protection
Fully transparent safety observation window with yellow high-visibility protective barrier prevents accidental contact with moving platens. Top tri-color warning light signals standby/running/fault status; physical emergency stop button cuts all motion instantly. Four vertical guide posts ensure stable vertical movement to avoid mold offset during clamping.
6.Robust Integrated Cabinet & Flexible Customization
Whole frame adopts seamless steel welding with high-temperature anti-rust baking paint finish, resistant to heat and chemical splashes. Adjustable leveling foot pads stabilize the machine on uneven lab countertops. Customizable platen dimensions, cylinder stroke, cooling water circulation system and special voltage configurations are offered for global clients.

Place metal mold filled with weighed rubber/silicone/plastic pellets onto the lower heating platen, close the safety observation door.
Set target curing temperature, holding pressure, vulcanization duration and auto exhaust cycles via touchscreen, activate preheating to stabilize platen temperature.
Hydraulic cylinder drives upper platen down at low speed to fit the mold, then switches to high-pressure clamping as preset.
Machine holds constant pressure for set vulcanization time, automatically lifting the platen slightly at programmed intervals to vent trapped air.
After curing countdown completes, the cylinder retracts to fully open the platens; take out finished molded sheets or small parts for cooling.
Wipe residual polymer from platens, inspect hydraulic oil level and heating tube status before shutting down power.
