In the field of powder molding, screw press as an important mechanical equipment, with its wide range of applications and excellent performance, to solve many problems in the production of products. This article will illustrate the excellent performance of screw presses in solving common problems in the field of powder forming through a practical case study.

Common problems in the field of powder molding

Uneven density: In the powder molding process, due to the difference in the size, shape and fluidity of the powder particles, the density of the product is often uneven, affecting the quality of the product.

Prone to cracks: Due to factors such as stress concentration and excessive cooling speed in the powder molding process, products are prone to cracks, affecting strength and appearance.

Low production efficiency: Traditional powder molding methods generally use molds or presses, which have low production efficiency, and the replacement and maintenance of molds also increase production costs.

Second, the excellent performance of the screw press in solving these problems

Improve the density uniformity: The screw press adopts the spiral propulsion method, which can push the powder particles evenly to the mold and improve the density uniformity of the product. At the same time, the screw press has an adjustable compression ratio, which can adjust the pressure and stroke according to the product requirements to further optimize the product density.

Reduce cracks: The screw press adopts axial pressure instead of traditional radial pressure, which can effectively reduce the stress concentration inside the product and reduce the generation of cracks. At the same time, the screw press has a slow pressure speed, which can better control the flow and cooling speed of the powder and avoid cracks caused by rapid cooling.

Improve production efficiency: The screw press can achieve continuous automated production and improve production efficiency. At the same time, the mold replacement and maintenance of the screw press is relatively simple, which can save a lot of time and cost.

3. Practical case analysis

A company produces a precision part that requires powder molding. Because the traditional processing method has problems such as uneven density and prone to cracks, the company decided to use a screw press for production. By using a screw press, the company has successfully solved the problems of traditional processing methods. Specifically, the uniformity of product density is significantly improved, while the number of cracks is significantly reduced. In addition, production efficiency has been greatly improved, saving the company a lot of time and costs.

Screw press has a wide range of application prospects in the field of powder molding, and its excellent performance solves many problems in the production of products. By improving density uniformity, reducing cracks and optimizing production efficiency, screw presses have brought important technological advances and economic benefits to the field of powder forming. Therefore, for companies and individuals engaged in the field of powder molding, it is very necessary to understand and use screw presses.
