Extrusion Forming

Radiators plays a crucial role in thermal performance of LED Lamp, and the latest development of LED honeycomb radiator forming process has been discussed. Moreover, stress-strain state in the dies and blank flow condition with different die structures have been studied by DEFORM. Accordingly the feasibility of the optimization design also has been demonstrated. The results show that the substance flowing has a serious affect on the force to the die. And with an appropriate die structure, the uniformity of forming can be greatly improved and the force to the die can be reduced.

Stamping Part

Press-extrusion forming is a combined extrusion process for forming embossment on metal sheets. A series of simulations on embossment forming using the program DEFORM were carried out. It is shown that the optimal process, the suitable die structure and the friction conditions can form embossment on the stamping part with good dimensions. The experiments conducted in the present study not only validated the finite element analysis but also confirmed the efficiency of the suitable die structure in helping the embossment formation.

In the investigation, the continuous extrusion forming (CONFORM) process of aluminum alloy rectangular hollow conductor has been studied by three-dimensional finite-element method based on Software DEFORM-3D. The rigid-viscoplastic constitutive equation was employed in the model. Distributions of velocity field, strain field, stress field and temperature field were obtained in the forming process. The results will give effective guidelines to optimize the processing parameters and to select, the die structure and die materials.

Warm Extrusion

The problems of 3Cr2W8V steel concave die forging production must be solved, such as too many procedures, high cost and mold crack. Through the use of a warm extrusion forming method it could make one-off forming die cavity come true, more practical warm extrusion forming parameters and extrusion die structure parameters were obtained. A suitable lubricant was selected out so that the processed forging die organization was improved and forging streamline distribution was more rational. The service life of forging die increased, and warm extrusion forming technology was applied in the mold production.
