110V Acrylic Bender, 300mm 12in Bending Machine

The 110V Acrylic Bender offers adjustable temperature through a thermostat, enabling precise heat application to acrylic, organic board, PVC, and other thermoplastics up to 6 mm thick. With a 300 mm (12 in) heating length and a safety water cooling design, this unit aims to minimize thermal deformation, heating only where needed. Its compact form makes it suitable for shop spaces that require reliable, on-demand bending capabilities.
Acrylic PVC Plastic Bender 110V

This 110V bender is designed for thicker work by enabling two plastic bending strips to heat top and bottom sides simultaneously. It features water circulation cooling on both sides of the heating tube to prevent unwanted deformation. It is compatible with acrylic, organic board, PVC, and various thermoplastics, offering a practical approach for sign making and display projects that demand precise curvatures.
JINHZIXIU 24 Inch Bending Machine

JINHZIXIU offers a 24-inch acrylic plastic PVC bending solution with dual heating, water circulation cooling, and uniform temperature control. The unit is described as portable and space-saving, capable of hot bending plastic sheets thicker than 6 mm when configured with multiple heaters. It can be paired with a worktable for a larger hot-bending setup or used standalone for targeted bends.
12inch 30cm Acrylic Bending Machine

This 12-inch model provides adjustable temperature with water-circulation cooling for uniform heating. Portable and practical, it supports bending various plastics with a thickness up to 6 mm. The design emphasizes safe power and water connections, ease of plug-in assembly, and straightforward operation alongside a workbench for stability during bending tasks.
ABS Plastic Rectangular Solid Bar

Although not a heat bar, this 2″ x 3″ x 12″ ABS block is included as a practical material for prototyping and fixture building. It is described as durable and versatile for machining, modeling, and project development when paired with bending setups for test fits and sample components.
Buying Guide
Key factors when choosing a heat bar or bending setup for plastic include heating capacity, temperature stability, and cooling effectiveness. Look for adjustable thermostats and uniform heat distribution to avoid warping. Water-cooling systems help prevent thermal deformation and extend component life, especially for thicker sheets. Consider the sheet thickness you work with most often (typically up to 6 mm for these models) and whether you need dual heaters to heat both sides simultaneously on thicker materials.
- Thermal control: Precise temperature adjustment reduces the risk of scorching or under-heating.
- Cooling: Active water cooling minimizes deformation and supports longer tool life.
- Sheet compatibility: Ensure the unit supports your common plastic types (acrylic, PVC, thermoplastics).
- Heating length: Longer bars enable larger bends; shorter bars are more portable.
- Safety: Look for water safety isolation, stable stands, and easy handling to protect operators.
- Expandability: Some models support multiple heaters or modular additions for more complex bends.
- Portability: If space is limited, prioritizing compact, lightweight designs helps maintain workflow efficiency.
