|Metamold vs Vinyl Ester|
Gruber Systems offers two types of mold construction for use in cultured marble, or solid surface casting (manufacturing) applications. Each uses a different gelcoat technology. Before ordering a mold from Gruber, you should consider which gelcoat finish you prefer:
Metamold or Vinyl Ester Molds - which is right for you?
Any mold ordered must have the type of construction specified on the part number
To order MetaMold mold construction, add an "M" to the end of the part number
Using a Mark 60 bathtub mold as an example, to order a Metamold version, order 29060M
To order Vinyl Ester (VE) mold construction, add a "V" to the end of the part number
Using a Mark 60 bathtub mold as an example, to order a Vinyl Ester (VE) version, order 29060V
Metamold is the preferred choice for demanding applications where durability is the key consideration. For only a small cost difference, you get the highest performance gelcoat material on the market for solid surface and cultured marble casting. In fact, Metamold is the ONLY choice recommended by Gruber for solid surface production due to its ability to handle higher exothermic temperatures created with solid surface material processing. The distinctive grey metallic color identifies Gruber’s proprietary gelcoat and the Metamold option. This metallic composite surface, combined with state-of-the art lamination techniques and specialized box construction, is an option you will want to include on all of your Gruber mold orders.
Metamold’s metallic composite gelcoat provides greater surface strength. Greater surface strength means the original high gloss finish is retained longer.
Metamold’s metallic composite gelcoat provides improved chemical resistance. Improved chemical resistance:
Other MetaMold benefits:
This mold is warranted to be free of any manufacturing defects. When used in accordance with these instructions and recommended materials and processes, this mold should produce hundreds of cast polyester castings of high quality. This warranty expressly does not include damage caused to the mold because of gelcoat or matrix that sticks to the mold. (This is a function of the mold preparation and release system used.) No other warranty, expressed or implied, is assumed nor will be assumed.
Vinyl Ester (VE) Gelcoat
Vinyl Ester is ideally suited for low production shops (turn molds once a day). VE, although not as tough as META, will give many years of trouble free service at a reduced cost.
