Extrusion

Extrusion is a process used to create objects of a fixed cross- sectional profile. A material is pushed or drawn through a die of the desired cross-section. The two main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections and work materials that are brittle, because the material only encounters compressive and shear stresses. It also forms finished parts with an excellent surface finish.

Extrusion may be continuous (theoretically producing indefinitely long material) or semi-continuous (producing many pieces). be done with the material hot or cold.

Extrusion remains a popular choice for many manufacturers because of the neat, uniform way extruded rubber products can be produced. A great variety of shapes can be created for any industrial need, including hollow designs that greatly reduce material cost and create flexible, lightweight product.


HOT FEED EXTRUSIONS
Hot feed extruder involve pre-heating the rubber material/compounds before the extrusion process. These extruder help to form and shape rubber compounds which can further be used for manufacturing final products having required characteristics such as strength and durability.


CONTINUOUS VULCANISATION LINE- EXTRUSION
Continuous vulcanisation has the advantage of combining processing and curing steps into one continuous operation on many extruded profiles. Traditionally, extruded profiles and hoses have been separately processed and vulcanized. During the processing step, the profile is extruded in a continuous operation, but the extrudate is accumulated for later batch vulcanization, in a steam autoclave.

Basically there are four stages to the continuous vulcanization process:
1. Formation of the profile.
2. Heating to cure temperature.
3. Curing.
4. Cooling.

Heat may be generated by heat transfer from the outside (Hot Air, Fluid Bed, Liquid Curing Media (LCM). Curing is achieved by maintaining the temperature for the time needed to fully crosslink the rubber.



SAFETY PRODUCTS
The fender system is of a flexible Rubber which offers a high resistance to the environment and mechanical properties that have a high degree of elasticity and resistance. A sound fender system is critical to knowing that your property is well protected from the impacts . All the better is a system that also offers easy installation, easy maintenance, time and cost savings.


This fender system is designed for impact protection that minimizes the force transmitted to the structure, being capable to absorb the energy with higher displacement and less reaction force.
