How to make a good acrylic bathtub

First step: prepare for the making machines and molds

The acrylic bathtub making need the devices as follows,

1. acrylic bathtub vacuum forming machines--9800USD/set

2. bathtub forming molds(good designs)--about 850USD/set

Made in FRP materials, 2 years guarantee

3.resin mixer(thermostatic resin mixer)--2250USD/piece,simple mixer: 650USD

 or 

4. resin spray gun with fiber chopper(automatic)--5500USD/set

The details of the spray gun for fiber glass and resin are as follows,

Using material: calcium carbonate(CaCO3) powder,resin,solidifying chemical(catalyzer,catalyst)

1:Maximum injection: 15Kg/min

2:Resin injection: 3.5——5Kg/min

3:Fiber glass: 1.5Kg/min

4:Pressure ratio: 18:1

5:Range of pecentage of solidifying chemical: 0.8——3%

6:Working pressure: 0.3——0.6Mpa

-----------------------------------------------------------------

The spray gun advantages:

1.Accurate ratio control. Catalyst slave pump for exact catalyst ratio ensures the parts cured at desired rate.

2.Environment friendly. Airless spraying decreases the volatilization and less pollution.

3.Cart & System. The whole system is mounted on a cart chassis which makes the equipment moveable, benefits the spraying flexible.

4.Roving management. The roving is guided by the boom crutch to make the roving smooth, less tangling, more uptime.

5.Compact & light weight.

6.American Gun available.

7.One year guarantee.

5. bathtub edge trimming machine--5600USD/set

Second step: prepare for the bathtub making materials:

The acrylic bathtub need the materials as follows,

1. Acrylic sheets(you also can choose acrylic, ABS composite sheets)
The thickness: 2.3mm, 2.5mm, 3mm, 3.2mm3.5mm, 4mm, 4.5mm
Can be with colors
Acrylic sheets looks more bright

The acrylic sheets parameters:

Product Paramenters

2. Resin
DC191, to make the reinforcement together with the fiber glass

  

3. Fiber glass
To make the reinforcement together with the resin
Specifications: 300G/M2, 250G/M2, or 400G/M2, or roving fiber

4. Stone powder(calcium carbonate powder, CaCO3 powder)
Mixed with resin, as the filling materials for the mixture of the resin and fiber glass reinforcement
With very cheap price, you can buy it in your own country

5. Catylist for the resin chemical action

The blue chemical(mixed with resin and stone powder) and the white chemical(add the white chemical when you want to spray the materials), with these two chemicals, the resin will turn into hard quickly.

Third step: connect the mold to the vacuum forming machine and make the vacuum formings,

Fourth step: rough cutting the bathtub edges and make the fiberglass and resin reinforcement:

The bathtub need the 3 layers of resin and fiberglass reinforcement.

The resin will turn into hard about 2 hours later, then can make the edge cutting/trimming.

Fifth step: make the bathtub edge cutting/trimming
