Hose extrusion lines

Turbo Charger Intercooler (TCI) Hose Lines

Colmec designs and builds complete systems for the production of turbocharger hoses for the automotive industry. The turbocharger hoses are used to convey high-pressure air both in the suction and compression phases and are made to withstand hydrocarbons and oil particles that could form in the cooling compressed air.

The inner surface of the tube is protected with a layer of a few tenths of a millimeter thick with fluoridated rubber or fluoridated silicone to improve its durability. Internal protection is obtained by co-extrusion between fluoridated rubber and silicone or between fluoridated silicone and silicone to which a textile reinforcement in aramid fiber and a final silicone coating is applied.

SPECICATIONS

• Extrusion and knitting speeds of up to 20 m/min
• The inner diameter of the TCI pipe up to 150 mm.
• Inline knitted reinforcement

Applications

Gasoline Hose Lines

These lines are based on state-of-the-art technology and can be provided in different configurations that allow you to realize different product types. They are generally extruded on a flexible mandrel and are made up of a thin substrate barrier that is impermeable to fuel with textile reinforcement and rubber coating.

SPECIFICATIONS

• Extruded on flexible mandrel
• Multilayer hose with fluoro-plastic barrier
• Co-extruded with fluoro-elastomers
• Textile reinforcement

Applications

Radiator Hose Lines

Radiator hose extrusion lines are able to continuously produce the preformed tube before being shaped and vulcanized. The extruded hose meets the highest quality standards and are of uniform thickness and regular appearance of the inner and outer surfaces.

SPECIFICATIONS

• Extrusion and knitting speeds of up to 20 m/min
• Internal diameter of the radiator hose up to 120 mm
• Inline knitted reinforcement

Applications

Air Conditioning Hose Lines

Extrusion line for Verner type hose
This type of extrusion consists of an internal polyamide PA layer to minimize the permeation of refrigerant gas, rubber coating, textile reinforcement and final rubber coating.

Barrier tube extrusion line
This type of extrusion consists of an inner layer of rubber, coated with polyamide PA to minimize the permeation of refrigerant gas, rubber coating, textile reinforcement and final rubber coating. Application for this product are in air conditioning systems of cars, trucks, buses and commercial and industrial air conditioning systems.

SPECIFICATIONS

• High-strength knitted or braided textile reinforcement
• Internal diameters from 5/16″ to 1 1/4″
• Operating pressures up to 35 Bars

Applications

High Pressure Hose Lines

High pressure hose extrusion lines consist of a wide range of machines and accessories that can be configured for full production flexibility. This type of hose is used for hydraulic such as mineral oils, lubricants and hydrocarbons at high temperatures.

SPECIFICATIONS

• Extruded on rigid or flexible mandrels
• High-strength braided textile reinforcement
• Internal diameters from ¼” to 1 ¼”
• Operating pressures: 40 – 350 Bars

Applications

Low Pressure Hose Lines

Colmec provides a full range of low-pressure hose solutions with high line speeds and minimal energy consumption. These types of hoses are used for the passage of oil in hydraulic systems, oxygen and acetylene for welding systems, compressed air and inert fluids for industrial compressors and pneumatic tools.

SPECIFICATIONS

• Extruded without a flexible mandrel
• Spiral textile reinforcement
• Internal diameters from ¼” to 1 ¼”
• Operating pressures: 10 – 35 Bars

Applications

“Multifuntional” Hose line

It is a line structured to be able to produce different types of rubber hoses:

• Low pressure hoses with spiral and/or knitted reinforcement
• High pressure hoses with off-line braiding reinforcement
• Air conditioning hoses and fuel hoses with also internal layers of thermoplastic material such as THV, PA . To guarantee a smooth surface of the hose after the curing process the line is completed with an covering extrusion in PP and/or TPX
