Description
Lab Rubber vulcanizing press machine is also known as hydraulic press machinery or rubber vulcanizer.
The vulcanization process improves the elasticity, hardness, tear strength, and resistance for rubber material to organic solvents and abrasion. It also offers excellent resilience, low water absorption, and oxidation resistance and makes an excellent electrical insulator.
The laboratory vulcanizing press machine is widely used mechanical product in the rubber ,silicone,plastic industries. It is suitable for vulcanization and restriction of various rubber and plastic products. Fully automatic rubber vulcanizer is controlled by PLC with computer automatic detection system, user-friendly programming design, can automatically complete mold, forced mold opening, mold transfer, vulcanization timing, exhaust time and frequency setting, front belt flap, mold lift Repeatedly ejecting equipment and other functions.
According to different needs, there are three kinds of hydraulic press machines, they are column type, frame plate type, jaw type, and other styles.
The rubber vulcanizer machine mainly comprises of a host, hydraulic station, electric control system. It has a device of pressure, time, and automatic temperature control system.
These vulcanizing press machines are mainly for rubber vulcanization, thermosetting plastics and insulation products of pression, it is widely used for R & D in laboratory and college or university lab or institute. It is appliable for rubber(include raw and synthetic rubber ), plastic, silicone material.
The hot plate and plunger are made of quality steel material, which features high wear-resistance and durability. The vulcanizing press machine can be equipped with model pulling and pushing devices to reduce work strength based on product requirements.
When processing, the raw materials is put into the mold between the electric boards, you need to set certain pressure and temperature.
The vulcanizer press can be used to produce many products ,such as seals, O-rings, oil seals, rubber pads, thermosetting plastics, foam, resin, building materials and other rubber and plastic products. It is a leading and reliable automatic equipment for rubber and plastic vulcanized products.
We stock and can custom-made all kinds of rubber vulcanizing press machines, ranging from 10ton,20ton, and 300ton

What Is Vulcanized Rubber Used For?
Vulcanization gives rubber its characteristic more elastic and durable quality ,it is vital for rubber,silicone,plastic polymer industries . the vulcanized rubber material can be used to produce many products ,including soles of shoes, hoses, hockey pucks, bowling balls, toys, tires, bouncing balls, and much more.
How Do Vulcanizing Press Work?
Vulcanisation is a thermochemical process which is vital for rubber industries. The rubber vulcanization includes a series of complicated chemical reactions with sulfur,accelerators and additives,it promotes cross-linking between rubber molecules , in order to improve the strength, abrasion, and aging resistance of the rubber. The vulcanized rubber material become more flexible ,elastic and durable than rubber that has not been vulcanised.
On the process of vulcanization , the rubber material are placed between two flat heated to a specified temperature . After high temperature and high pressure ,the rubber vulcanization is pressed into the desired shape . Here is the process of vulcanization as follows:
1. Pre-treament for Material :the rubber material to be vulcanized needs to be pre-treated, for example the material should undergo these process ,such as rubber cutting, crushing & blending, and mixing & kneading.
2. Charging and Loading Mold :the material treadted are sent to the rubber vulcanizer equipment for curing .The material are usually mixed with additives such as vulcanizing agents, accelerators, preservatives, and fillers to form a uniform rubber mixture.
3. Setting Heating & Pressure :Set some certain temperature and pressure ,process time for the vulcanization machine,which are controlled by PLC system .
Basically ,the vulcanization temperature can be adjustable as per different rubber materials and vulcanization requirements （）between usually between 140°–180° ). The vulcanization time is usually longer and can last from a few minutes to several hours.
4. Cooling and Curing: When the vulcanization reaction is completed, the hydraulic vulcanizing press machine starts the cooling system to cool the vulcanized rubber products, to cure their shape and structure.
Application of Vulcanization
The vulcanized rubber material feature higher tensile strength and thermal stability and durability ,it is 10 times more stronger than natural rubber. The vulcanized rubber material can be widely used to produce many products ,including
