Olimy hand lay up custom fiberglass truck body molds

Mould treatment: 

Polish: Moulds must be polished before production. This will guarantee the good and solidified surface
Clean: Special detergent are used to get the dust away from the mould. This will make no dark markings in the gel coat surface. 
Release agent: This will be brushed on the mould to make demoulding easily.

Fiberglass and resin:

Gel coat: The color is decided by the gel coat,with thickness of about 0.3-0.5mm. UV resistant can be added. 

Surface mat:  This is to avoid the air bubble on the surface, and also make fiberglass mat  invisible from the finished surface. 

Fiberglass mat: Normally we use 300g/m2 (0.6mm thickness) and 450g/m2 (0.9mm thickness). Accordig to your requests on the thickness and strength,we will calculate how many layers of fiberglass mat should be used.

Demould and trim:

Solidify:  The time required for solidifying depends on thickness and weather condition.Normally 24 hours for one piece to solidify to avoid any deformation after demoulding. 

Demould: After solidified, the product will be demoulded

Cut and trim:  We will mark the trim line and hole positions on the mould,then trim according to the marks to gaurantee the mounting dimensions

Air bubble test and repair 

Air bubble test: Every piece will be put into the oven under 44 celsius degree for about 20 minutes,so that the air bubbles can break out then our workers will repair the surface. 

Repair and surface treatment: we will make the air bubble repaired and treat the surface with average gloss.

Packaging:  1.Air bubble packaging

                     2.Plywood Crate or shelf packaging
