Laboratory 10/30/50 Ton Hydraulic Vacuum Flat Vulcanizing Press Machine For Rubber Forming
Overview
This series of plate vulcanizing machines is designed as a primary equipment for molding both shaped and non‑shaped rubber products. It is also suitable for pressing various thermosetting plastics and foam rubber/plastic products. Equipped with an independent power mechanism and electrical system, the machine adopts centralized push‑button control. Both working pressure and heating temperature can be adjusted within a specified range. The machine is available in manual and semi‑automatic versions.
Heating Plate Features
Constructed from imported high‑temperature‑resistant steel, the surface is treated with deep carbonization and hard chrome plating, offering fast heat transfer, rapid cooling, corrosion resistance, high hardness, and minimal deformation. The rear side incorporates built‑in heaters and temperature sensors, providing high power, quick heating, sensitive and uniform temperature detection, and a narrow temperature error range.
Guide Pillars
Four hardened and precisely positioned pillars, together with hydraulic cylinders, are supported by a thick steel‑plate base of the entire control cabinet, forming the hydraulic platform. The platform slides smoothly and quietly on self‑lubricating bronze bearings. The top and rear of the press are enclosed by heavy‑duty steel plates, offering additional safety protection for operators. The upper plate is made of steel and includes an insertion‑type thermocouple near the surface.

Operating Procedure of the Testing Machine
1. First, level the testing machine by placing a level gauge on the machine base. Adjust the foundation screws according to the level indicator until the machine is perfectly horizontal (perform this adjustment when installing or relocating the machine).
2. Turn on the main power switch to supply electricity to all control panels of the machine.
3. Set the required test temperature.
4. Based on the sample requirements, set the temperatures for the upper, upper-middle, lower-middle, and lower molds respectively. Once the temperatures reach the set values, open the cylinder door and place the heat‑insulating stainless steel plate and the sample.
5. Press the start test button to initiate the test by raising the hydraulic cylinder platen (do not adjust the hydraulic system pressure and speed arbitrarily).
6. The system will automatically reset when the set time is reached.
7. Observe the sample condition to confirm the test is completed.
