Composite Manufacturing

• Produces parts with high strength, stiffness, and dimensional accuracy
• Good surface finish and low void content
• Suitable for large and complex parts with tight tolerances
• High repeatability and quality control

Vacuum Infusion

Vacuum infusion is a low-pressure process that involves the use of a vacuum bag to draw resin into a mould. In this process, a dry fibre reinforcement material is placed in a mould, and a vacuum bag is sealed around the mould. The vacuum is then applied to the bag, which draws resin through the reinforcement material and into the mould. This process is used for producing large, complex parts with good mechanical properties.
Advantages of Vacuum Infusion :

• Produces parts with good mechanical properties and low void content
• Low material waste due to precise resin placement
• Suitable for large and complex parts
• Lower cost than autoclave molding

Vacuum Bag Molding

Vacuum bag moulding is similar to vacuum infusion, but it uses atmospheric pressure instead of a vacuum to compress the material in the mould. In this process, a dry fibre reinforcement material is placed in a mould, and a vacuum bag is sealed around the mould. The air is then removed from the bag, which applies atmospheric pressure to the mould, compressing the reinforcement material and allowing the resin to be drawn into the mould.
Advantages of Vacuum Bag Molding :

• Lower cost than autoclave molding
• Suitable for producing small to medium-sized parts
• Good surface finish and low void content
• Good mechanical properties

Compression Molding

Compression molding employs a hydraulic press to exert high pressure on a mold, effectively compressing the reinforcement material and resin together in the process. In this process, a dry fibre reinforcement material is placed in a mould, and resin is injected into the mould under pressure. The mould is then heated, causing the resin to cure & bond the fibres together. This process is used to produce parts with complex shapes and good mechanical properties
Advantages of Compression Molding :

• Produces parts with good mechanical properties and dimensional stability
• Suitable for producing large parts with complex shapes
• Low material waste due to precise resin placement
• High repeatability and quality control

Pultrusion

Pultrusion is a continuous process used to produce composite parts with a constant cross-section, such as rods, tubes, and beams. During this process, reinforcement fibers are drawn through a resin bath and subsequently passed through a heated die. The die serves the dual purpose of shaping and curing the composite material as the fibers progress through it. This process is used to produce parts with a high strength-to-weight ratio and good mechanical properties.
Advantages of Pultrusion :

• High production rates and continuous manufacturing
• Good mechanical properties and strength-to-weight ratio
• Consistent cross-sectional dimensions
• Low material waste due to continuous process
