Hot forming application mold resin

Manufacturing technology of air thermoforming mould

1、 Production of liquid epoxy mold resin (hand paste molding)

1. Prepare the model -- the wood model is processed with jrj700 wood substitute CNC or our paste wood substitute sw325

2. Process the main model

2.1 sealing -- ETI resin spray & sealer

2.2 apply release agent dh9719 (paste release wax)

2.3 polishing

2.4 repeat 2.2-2.3 three times

3. Brush the mold gel coat rg515 (gray) brush the surface gel coat with a hard brush to ensure that each place is painted in place (0.5-1mm)

4. After waiting for gel coat gel (about 30min), cover the transition layer resin (ec715+ aluminum powder) for 10-15mm

5. Place cooling or heating water pipes, usually copper pipes wrapped with tin paper, placed on the transition layer and coated with transition layer resin;

6. Put the prepared mold frame in place (as needed) (the mold frame needs to be welded with reinforcing bars and anchors) and fill it with laminated resin (ec715 + aluminum powder + aluminum particles) or for large molds that need light structure, use laminated resin + glass cloth (generally about 10 layers)

7. The mold can be demoulded after curing at room temperature for 24h. After finishing the demoulding, put the mold into the drying room for post curing:

40 ℃ /4h+60 ℃ /2h+80 ℃ /2h+100 ℃ /2h, and then the mold is naturally cooled in the oven to room temperature to drill (vacuum gas path)

2、 Using temperature resistant Machinable substitute wood obo652ht for direct CNC processing - subsequent drilling is required

3、 Direct CNC processing with temperature resistant microporous Machinable plates (no drilling required)

Our microporous Machinable plates have microporous characteristics, and drilling is no longer required. Its micro permeability replaces the forming / demoulding vent required by traditional tools (molds for deep drawing plastic films and plates). Plates can be easily bonded to combine large and deep drawing dies or to connect aluminum frames. Many types of microporous composite Machinable plates can be used to solve your challenges. (different pore sizes and porosity) the temperature resistance of the plate can reach 240 ℃
