A making vulcanizer is an essential piece of equipment used in the rubber industry to undertake the vulcanization process, i.e., curing or hardening of the rubber. This apparatus not only shapes and molds the rubber but also proposes a heats transfer system that enhances the bond formation between the molecules of the rubber.
Hydraulic vulcanizer:
A hydraulic vulcanizer is an apparatus that uses hydraulic pressure for curing and rubber molding. The rubber material is mainly used in molds to make the product shape. Then, the mold is enclosed and subjected to heat either internally by using electrical elements or externally by hot water from a hydraulic power pack. The rubber is vulcanized by applying hydraulic pressure through the hydraulic power pack that pushes the mold down. This pressure ensures that the rubber fills the mold completely, eliminating any air spaces that can form. Once the rubber vulcanizes, the mold can be opened, and the product removed.
Hydraulic press vulcanizer:
The hydraulic press vulcanizer allows users to easily place the rubber in the mold. Users must close the press to start the vulcanization process. It is important to note that the hydraulic press vulcanizer's capacity is greater than that of a makeshift vulcanizer. This means multiple items can be cured at once or larger items voluminous.
Manual vulcanizer press:
The manual vulcanizer press is molded using handles and levers. It has two large plates, the upper and lower platen, in which the mold is placed to start the curing process. Once again, heat and pressure are applied to the mold through the manual lever system. Compared to hydraulic presses, the process is slower, and more molds are used.
Liquid nitrogen vulcanizer:
A multifunctional, portable apparatus allows users to quickly and more importantly, safely cure rubber under pressure using liquid nitrogen. Users can actively engage in rubber vulcanization wherever they are.
Electric vulcanizer:/strong>
An electric vulcanizer has an electric heating element to supply heat during the curing process. It is more energy efficient than oil and steam appliances. The vulcanizer has a touch screen or buttons to more precisely control temperature and pressure.
Step flange vulcanizer:
In the step flange vulcanizer, the heating element flanges are molded up to 10,11, and 12 pieces. It molds rubber products with steps or ribs like flanges and pants. Additionally, the vulcanizer can be adjusted and customized per the customer's needs.
Plate size:
The plates on the vulcanizing machine will vary depending on the size and type of equipment being vulcanized. For example, gym mats may use a plate with a 20x24 or 20x30 size while larger tires will use plates up to 3.5x9.5 feet in size.
Capacity:
The capacity refers to how many vulcanized items can be processed in one cycle. For example, bench presses can take up to eight mats per cycle, while smaller gym mat vulcanizers can only handle one matr at a time. This also depends on the plate size and power of the vulcanizing machine.
Temperature:
Operating temperatures for vulcanizers fall between 113 to 159 degrees Celsius (235 to 318 degrees Fahrenheit). This vulcanizing temperature helps form a rubber that is resistant to solvents, chemicals, and wear, extending the life of the gym mat. Some machines can go up to 177 degrees Celsius (350 degrees Fahrenheit).
Power:
The power of vulcanizing machines ranges between 8 to 40 HP (horsepower). More powerful machines are larger, have more capacity, and process items faster. For example, a gym mat vulcanizer will use around 10 HP of power, while marbles, which are larger, may use 20 HP.
Hydraulic press:
This component puts pressure and holds the items in place while they are being heated and fixed. The force or pressure it exerts is calculated using the area/size (in square inches) multiplied by the PSI (pounds per square inch). For example, a large tire vulcanizer would need a lot more hydraulic force than smaller gym mat ones.
Vulcanizing kits:
These are kits used in emergency tire repairs containing the tools to fix the vulcanized part. The kits include plugs, sealant, and tire repair tools like reamers and insertion tools.
Proper maintenance ensures that the gym mat vulcanizing machine or tire vulcanizer machine will work for a longer period of time and at optimum efficiency. Here are some maintenance tips:
Regular inspection:
Operators should carefully inspect the machine on a routine basis to look for damages, loose parts, wear and tear, or anything unusual. Fix any issues immediately to prevent further damage.
Lubrication:
Tires and other rubber products have to be lubricated pre-vulcanization so that they do not stick to the plates. This includes using release agents like soapstone or talc. Maintain lubrication of moving parts of the machine like chains, rollers, and bearings as well.
Cleaning:
Remove any residue build-up on plates after each use. Clean with a suitable non-corrosive cleaner. Vacuum debris from the machine.Abrasion cleaning kits are available for gym mat cleaning. Use the dual action compressor and mat cleaning solution to clean These should include the tire repair service not necessitating the use of a gym mat one.
Calibrate:
Temperature and pressure need to be set according to the item being vulcanized. For example, gym mats require 10 HP of power at 235 to 318 degrees Fahrenheit. Larger items like tires will need a lot more power and different temperatures.
A vulcanizer is used widely in different industries and applications as outlined below.
Tire Repair
Mobile vulcanization units are primarily used in the tire industry for repairs.
They offer an effective approach to fixing punctures, improving longevity, and restoring functionality.
Tire Production
The vulcanizer is essential in manufacturing tires for vehicles and other equipment. It helps to control pressures and temperatures when handling various materials like rubber and other complex polymers.
Toyotomi and auto buses use tires made with a vulcanizer. The durable and strong tires undergo less wearing and tear.
Industrial Equipment Repair
Heavy machinery used in mining, construction, and manufacturing industries often uses equipment made with the help of a vulcanizer. Examples include conveyor belts, hoses, gaskets, and seals.
Sporting Goods Manufacturing
Easily damaged items like inflatable balls require a vulcanizer during manufacturing. For example, the NFL footballs are made with a vulcanizer to create a tough exterior and well-rounded inner bladder to offer precise functioning.
A suitable vulcanization machine can improve production efficiency and increase profits. When looking for a vulcanizer, check the factors below.
Production capacity
Vulcanizers come in different sizes and production capacities. The capacity determines the amount of product the machine can process within a specific time. Consider business needs and product demand to choose a vulcanizer with the right capacity.
Available space
Know the dimensions of the vulcanizer to see if it will fit within the premises. Check the supplier's installation instructions and the space needed for equipment servicing.
Staff familiarity with the machine
Consider the knowledge and experience of staff with vulcanizer machines. If existing personnel do not know how to use the new equipment, training costs will be an extra expense to consider. Choosing a vulcanizer model that staff is familiar with can reduce training expenses.
