Tips before sintered stone bending

Thermal bending properties of sintered stone

sintered stone are a type of hard material that, compared to metal materials, have poor plasticity and usually cannot be cold-bent or hot-bent. However, under specific conditions, sintered stone can become plastic when heated, allowing for thermal bending.

Methods and applicable conditions for thermal bending

Methods for thermal bending

Heat the sintered stone to a certain temperature to make it soft, then use tools to bend it into the desired shape. There are two commonly used methods for thermal bending: one is to use an electric heating plate to heat the sintered stone, and the other is to use a torch or oven to heat the sintered stone.

Applicable conditions for thermal bending

Thermal bending of sintered stone requires the following conditions to be met:

(1) The type and thickness of the sintered stone must be suitable for thermal bending.

(2) The heating temperature and time of the sintered stone need to be strictly controlled. Overheating can cause cracking or loss of original hardness.

(3) Appropriate tools need to be used to support the board during the thermal bending process to prevent excessive stress from causing cracking.

Precautions

The heating method and time must be properly controlled, and kept away from the fire source to prevent fires or other hazards.

During the heating process, the temperature and changes in the shape of the board need to be checked, and the heating time and bending force need to be adjusted in a timely manner.

Before thermal bending, the sintered stone needs to be thoroughly cleaned to prevent contamination from affecting processing quality.

The surface of the sintered stone may have cracks or defects after thermal bending, which need to be polished and repaired.
