Technology Introduction

Squeeze-casting technology is a process technology in which high mechanical pressure is applied to the liquid (or semi-solid) metal entering the mold cavity to form and solidify under pressure to obtain good quality castings (or ingots) . This technology is very suitable for the efficient forming and production of parts with high strength, high density, high toughness, high air tightness and high wear resistance. It is regarded by industry experts as one of the most advanced forming processes in the field of non-ferrous alloy forming and it can achieve an effective balance between quality, efficiency and cost, and can create considerable value for customers.

01

The first technological feature of squeeze-casting

Vertical injection: its advantage is to reduce entrainment, less gas content in castings, so the casting could be processed by T6 heat treatment. And the high pressure chamber fullness is 100%, so its concentrated aluminum, less oxidized inclusions, less early solidification.

02

The second technological feature of squeeze-casting

Slow mode filling: its advantage is to reduce entrainment and metal turbulence, and the castings contain less gas, so T6 heat treatment can be carried out to strengthen the performance of castings.

03

The third technological feature of squeeze-casting

High pressure to replenish shrinkage cavity: the casting is formed under high pressure, so the grain is refined, the structure is dense (the pressure is between 50-140Mpa)

04

The fourth process characteristic of squeeze-casting

Thick-wall castings forming: it is very suitable for casting production with 2~40mm thick-wall, with excellent quality.

Comprehensive Advantage

  • The 1st advantage

    It is suitable for the production of high-strength, high-toughness safety parts and structural parts.

  • The 2nd advantage

    It is suitable for the production of high air tightness parts (air pressure and oil pressure resistance), such as pump bodies and shells.

  • The 3rd advantage

    Good appearance quality, high dimensional accuracy, can reduce machining or even no machining, reduce margins, and facilitate surface treatment

  • The 4th advantage

    It is easy to realize the full automation and intelligence of the processes of soup, spraying, picking, punch lubrication, proportioning, integrity inspection, cooling, gate removal, burr cleaning, marking, conveying, etc.
