Corona treatment consists in modifying the surface tension of polymer based surfaces in order to enhance their wet ability using an electrical discharge.

Corona treatment is achieved by means of electrodes positioned above the film surface resulting in a substantial production of ozone. Thanks to our experience and as a result of continuous research, the solutions proposed by POLYTECH guarantee a constant quality and an outstanding stability

POLYTECH series of compound are successfully used for Holography, Corona Treatment , Tape Plant, Poly coating, Garmex, M.D.O NIP roller for Film Plant, Epoxy Coating etc.

We provide Spiral & Straight Groove rollers that have modular design and can be availed by the clients in numerous standard versions to satisfy variegated loads on applications. In this component, the spirals go up or down and can also be made reversible. Features like ease of installation, dimensional accuracy and long service life make this product a favorite of numerous clients.

Diamond Groove ( Checkered Rollers )

We have gained expertise in providing our clients with Checkered Rollers that are highly adaptable and are available in different shapes & sizes. Used in different sectors, our rollers are widely appreciated by the customers due to their high quality, superior performance and longer functional life. Furthermore, our rollers can be manufactured as per the specifications laid down by the customers for this Diamond Groove Rollers we have highly equipped automatic CNC Machine.

Cooling Roller comes with a hard chrome plated surface & Rubber coated roller. Cooled water passing through its Rotary joint cools the hard chrome plated surface area of the Roll. Standard Cooling Roll cools the contact area that touches the web materials. There are different types of Cooling Rolls like single shell, double shell jacketed type, spiral type. The Surface Cooling Roller results in varying effects in different type of Cooling Rolls. Rotary Cooling Roller has a shaft with inside hole to fix rotary joint. Bigger shaft diameter is recommended to avoid breakage of end shafts as end shaft having inside hole and uneven alignment or heavy tension on shaft result brakeage so bigger shaft diameter is recommended. We are called upon as one of the major Industrial Cooling Roller Manufacturers in Gujarat(india).

For hot laminating rollers (up to 220oC), we would recommend using a high-release silicone compound, as this compound is capable of withstanding such temperatures & non sticky properties.

For hot lamination rollers, where temperatures will not exceed 150oC (and high load, abrasion and wear are considerations), then we would recommend using a synthetic rubber compound. These could include Hypalon, Carboxylated Nitrile and EPDM.

Lamination applications, include:

• Paper laminators.
• Printed circuit board laminators.
• Dry film laminators.
• Cold lamination.
• Hot lamination.

With many years of extensive experience, rubber rollers are quickly and efficiently re-covered to insure minimal machine down time.Rollers are stripped and any old coverings are disposed of in an effective and ecologically safe manner. All necessary engineering work is carried out to client customization and specification. With the appropriate new, custom rubber cover, the roll is completed through our complete manufacturing and fabrication line from vulcanization and grinding, to custom grooving and final inspection. Polytech maintains the highest standard of quality inspection at every stage, and guarantees outstanding workmanship on rubber rollers of any kind.

Process of Re-covered Rollers

• Inspecting incoming rollers
• Repairing journals if necessary
• Stripping of old worn rubber
• Recoating with new rubber
• Curing
• Precision grinding
• Polishing
• Final inspection

polytech produced rubber roller are made out of special formulated rubber & processed in controlled environment for getting uniform rubber properties for various applications.

roller are basic and primary accessory for web process control in printing industries. Even surface, appropriate material of coating according to the application, uniform hardness over the surface along with precision workmanship play vital roll in performance of the rubber roller. Selection of roller type and coating material depend upon the application & the web material.

polytech provides its customers with an extensive range of compounds and solutions that respond to all critical roll covering. In most of these processes, the elastomer covered rolls play a dominant role. The choice of the correct type and roll covering is of great importance, not only for the production performance, but also for the quality of the end product.

in addition to this, our rollers find their applications in various industries like plastic , printing packaging, steel, paper, textile, plywood & various industries.
