PROCESSES

Jans Composites deploy various open and closed mould technologies for composite manufacturing and can advise suitability depending on product or customer applications.

The production processes used at Jans Composites include: -

Due to the range of processes and industries Jans Composites supply to, we utilise a range of materials to develop fit-for-purpose components and assemblies. These include fully-engineered resin systems to meet FST, environmental and structural properties dependant on application. With our own in-house mixing plant, our colour matching capabilities are boundless

 

Hand Lamination 

Hand lay-up is the most commonly used fabrication technique applied in the reinforced plastic industry. This process leaves the A surface of the part as a quality finish. Glass fibre mat is manually placed on the mould and impregnated with resin using hand rollers and brushes. Each layer is added individually until the required thickness is achieved. The laminate is then allowed to cure at room temperature

 

Chopper Spray-up

Also known as spray-up, this process is similar to hand-lay only the fibreglass is pneumatically sprayed onto the mould in short strands of glass, premixed in a combined stream with the resin before exiting the chopper gun. Once applied to the mould, workers then roll out the fibreglass to compact the laminate. This process leaves the A surface of the part as a quality finish and is suitable for large and high volume applications

 

Light Resin Transfer Moulding

Light resin transfer moulding (LRTM), is a closed mould fibreglass manufacture process. It provides a quality finish for both the A and B surfaces with high dimensional accuracy. This process has the benefit of manufacturing multiple variations of part size within a single mould and it provides the opportunity to add various core structures to the part

 

Vacuum Infusion 

During this process, the resin is drawn through the glass fibre using a vacuum pressure. This allows for greater control of the resin to glass ratio and so can result in a lighter and stronger laminate. Material wastage is also minimised through this process

 

Silicone Bagging

A silicone membrane is used on the part B surface to create the vacuum seal to the mould. This process is cleaner for the operators, and material wastage is reduced, resulting in more cost-competitive part costing. Silicone bagging gives better control of glass/resin ratio, and therefore more control over part strength and component properties. As well as a higher level of control over part thickness
