Rubber Vulcanization

At Tamor SMR Ltd, manufacturing of Rubber Bonded to Metal and Rubber Molded items is achieved through the processes of:

  • Injection Molding
  • Transfer Molding
  • Compression Molding

Tamor SMR takes the rubber, implements the various molding methods on its production floor and produces high quality, durable and reliable end products for industrial applications in Defense, Transportation and other Commercial sectors.

Injection Molding involves preheating the rubber compound while it's being processed through an extruder.  Using high pressure, the compound is injected into the mold cavity for a certain time, pressure and temperature.  Typical items include high quantity small products weighing between a few grams to several kilograms. Cycle time is relatively short and the injection presses and the molds are relatively expensive.

Transfer Molding is a technique that combines injection and compression molding technologies.  Transfer molding requires building a "piston and cylinder"-like device in the mold and squirting the rubber into it through small holes. When the mold is closed and under hydraulic pressure, the rubber is forced through the small hole into the cavity where it cures.  Transfer molding is usually used for heavier rubber parts or in places where it is desirous to shorten the cycle time and produce rubber with uniform properties.  Transfer molds are more expensive than the ones used in compression molding.

Compression Molding is the classic rubber vulcanization method. A defined excess amount of the bulk rubber compound is placed in the cavity of the mold. Using increased pressure and temperature, the rubber compound is formed. It is the excess material in the cavity that provides the required pressure. Molds are relatively simple and help in studying shrinkage of rubber and producing first samples of various rubber compounds.  This method is generally the most suitable method for low and medium sized serial production.

Deep Drawing Process

At Tamor, the manufacturing of wheels can require the application of up to 1400 tons of pressure as flat, shiny metal discs are inserted into the tool dies and a hydraulic press forms the steel to its appropriate thickness and depth - this can mean a deep drawn item of up to a thickness of 12.7mm and a depth of 170mm.

Deep drawing is a metal forming process that provides many challenges.  The result must be a metal shape without cracks, wrinkles or breakage.  As the manufacturer, we thoroughly evaluate the type of metal used, its thickness, the tool surface finish, the type of lubricant used, the size and shape of the blank (the flat metal part that will be deep drawn), the punching speed, draw radii, draw ratio, draw bead height and shape.

Welding Process

Depending on the application and the product being manufactured, Tamor factory welders are qualified for MIG welding, also known as Gas Metal Arc Welding and TIG welding, also known as Gas Tungsten Arc Welding.

TIG Welding is used to produce high quality precision welds offering low distortion and precise control of welding variables such as heat.

MIG Welding is considered to be a semiautomatic process. Long welds can be made without starts and stops. Primary shielding gases used are Argon and CO2 .

Tamor's welding stations offer flexibility and were built with the comfort of the welder in mind. As a product is being welded, the welder can turn and adjust the angles of the item enabling him better control throughout the welding process.

Throughout the manufacturing process, Tamor's Quality Assurance team ensures that testing parameters are met and upheld in accordance with the requirements of, among others:

  • Magnetic particle testing
  • Liquid penetrant testing
  • Non destructive testing
  • Leakage testing
  • Drop fall testing
  • Vibration testing

Factory welders are trained to work and qualified in accordance with European DIN standards as well as American AWS standards. Examples of Tamor's welding certifications include AWS D 1.1, AWS D 17.1 and DIN 6700 EN 15085-2 Class I (used particularly for the railroad industry).

Machining Process

Painting & Preservation Process

Depending on the requirements of a manufactured item, metal surfaces undergo several painting and preservation stages within the Tamor factory before emerging as corrosion free, finished end products.

In-house, Tamor offers:

  • Shot peening or sandblasting to remove rust and produce smooth surfaces
  • Chemical coating
  • Degreasing and rinsing
  • Painting with rust inhibiting primers
  • Painting with water based or solvent based paints
