FAQ
Q: Why choose vacuum forming process to make plastic bathtub?
A: Vacuum forming softens the sheet by heating and then adsorbs it on the mold surface for quick shaping. High efficiency and low cost, complex shape adaptation, high material utilization rate.
Q: Will acrylic ABS composite board deform or crack during vacuum forming?
A: No. The ABS layer softens at 80-140℃, and the acrylic layer has higher temperature resistance (about 160℃), ensuring a smooth surface without deformation; after forming, the cooling and shaping process (such as water cooling/air cooling) is used to enhance the structural stability and avoid the risk of cracking.
Q: How durable is the vacuum formed bathtub? Is it suitable for commercial scenarios?
A: Absolutely applicable. The ABS layer has strong impact resistance and can bear more than 300kg
Q: How long does it take to customize a special-shaped bathtub?
A: The cycle is divided into two stages:
Mold making: 7-10 days for new molds (extended to 15 days for complex designs);
Mass production: Vacuum forming a single piece takes about 5-8 minutes, and small batch orders can be delivered within 7 days.
Advantages of plastic bathtubs
Lightweight installation: The weight is only 1/5 of the traditional ceramic/cast iron bathtub, suitable for high-rise buildings or RVs with limited load-bearing scenarios.
Thermal insulation: Plastic has low thermal conductivity and can keep warm for more than 30% longer than metal bathtubs.
Corrosion resistance: Anti-scale, anti-corrosion by detergents, no risk of rust, suitable for high-frequency hotel bathrooms.
Flexible design: Can be integrated into a seamless shape to reduce the risk of water leakage and adapt to personalized spaces (such as special-shaped RV bathrooms).
Available services
Customized plastic sheet supply:
Provide acrylic ABS composite sheet (thickness 1-8mm), support surface treatment.
Optional color/texture customization to match the hotel/homestay design theme.
Vacuum forming processing:
Equipment: Large CNC vacuum forming machine, 7 days to produce mold (3-5 days to deliver prototype).
Process: Precise temperature control (ABS layer softens at 50-70℃, the specific temperature is related to the thickness of the sheet), to ensure that there are no bubbles or deformation on the surface after molding.
applications of plastic bathtubs
Hotels/B&Bs:
Demands: Quick installation, batch customization, easy maintenance.
Case: Chain hotels often choose standardized sizes, and acrylic ABS bathtubs can unify molds to reduce costs.
RV/Yacht:
Demands: Lightweight, earthquake-resistant and anti-bumping, and space-saving.
Case: RV bathtubs are often designed to be compact (such as folding or semi-embedded) to fit limited spaces.
Why choose acrylic ABS composite sheet as the material for bathtub vacuum forming?
Jiangsu Compound has been specializing in the production of plastic sheets for 18 years
The composite board of acrylic (PMMA) and ABS combines the core advantages of the two materials:
- Surface performance: Acrylic provides a smooth, high-gloss surface, is stain-resistant and easy to clean, and is rich in color and easy to process.
- Structural strength: The ABS layer enhances impact resistance and toughness, avoids the brittleness of pure acrylic, and prolongs service life.
During vacuum forming, the ABS layer is easy to shape after being softened by heat, and the acrylic layer maintains a flat surface; low density (about 1.1-1.2 g/cm³), lighter than ceramic bathtubs, easy to transport and install; 20%-30% lower cost than pure acrylic board, while meeting the needs of the mid-to-high-end market. This is also the reason why acrylic ABS composite board vacuum forming is suitable for plastic bathtubs
