Mold Production With Zero Shrink
ZERO Tooling System
• Fits 100% on master pattern
• Saves overtime and labor costs
• Low styrene ratio and low styrene emission formulations provide safer working environment
• Glossy, high quality surfaces on molds
• Long lasting molds
It provides fast mold production and superior match of the mold on model. This system allows the application of resin wet-on-wet which offers faster mold production time and labor savings.
It is possible to obtain high gloss, glossy molds with high mechanical endurance and chemical resistance. We recommend ZERO Tooling System for production methods like RTM and hand layup, where model-part match and surface quality are critical.
The application steps of mold production are described below.
Step 1 Model Preparation
Prepare master 3D pattern of the composite part in CNC machine or 3D printer.
Step 2 Preparation of Model Surface
Apply putty, primer and topcoat on master pattern surface.
Step 3 Mold Release Agent Application
Apply Polivaks N and Polivaks SIVI PVA liquid mold release agent on master pattern.
Step 4 Mold Gelcoat Application
Apply tooling gelcoat Polijel 272 / Polijel 220 on master pattern in two layers.
Step 5 Skincoat Application
Apply Polives 701-TA with glass surface veil or 225gr/m² CSM* after gelcoat.
Step 6 Polyester Application
Apply Polipol 321-ZERO wet on wet with glass fibers on skin coat. It is possible to apply 6 layers of 300 gr/m² CSM* or 4 layers or 450 gr/m² CSM* of glass fibers wet on wet. After exothermic reaction, wait for the lamination to cool down and continue until the desired thickness.
Step 7 Demolding
Wait 24 hours for the mold to cure on master pattern and install a frame in order to add structural stability. It is possible to demold after framing the mold.
Step 8 Prepare Mold for Production
Clean the mold and polish to obtain shiny appearance.
