What makes a good mold for vacuum forming?

Suitable materials for use in vacuum forming are conventionally thermoplastics. The most common and easiest to use thermoplastic is high impact polystyrene sheeting (HIPS). This is molded around a wood, structural foam or cast or machined aluminium mold, and can form to almost any shape.

Can fiberglass be thermoformed?

Fiberglass is what is considered a thermoset composite, whereas Thermoformed Plastic is a thermoplastic.

Can you vacuum form fiberglass?

A plastic production process that heats a rigid 2D sheet and uses a vacuum and pressure to form the plastic sheet (various materials) against a mold into a 3D shape.

Can Fibreglass be injection Moulded?

Long fiber injection is a process in which polyurethane resin and chopped fiberglass are poured into an open mold. Low compression pressure is then used to create complex parts in a variety of sizes. LFI takes a two-step process and makes it one-step.

What material do you use for vacuum forming?
