1. DIE CASTING

Die Casting technology is frequently apply to large quantity of small to medium size parts in which fine quality, well surface finished and dimensional consistency is extremely desirable. Choong Fei is competent more over specializing in nonferrous metal die casting manufacturing. Wherein all die casting parts provide by us is aluminium based alloys.

Casting which being produced by this technology will results in a more consistency. Owing to the fine surface finish and fine dimensional accuracy, most of the casting can be eliminate from post-machining. However, due to the requirement of precision, some casting may still require a very light machining to bring dimensions to sizes.

2. SAND CASTING

In recent year, sand casting technology has been intensified and expanded in advance due to it is still the most flexible way used to produce casting in high production volume.

Quality sand casting is highly determined by the foundry technique practice by sand caster. Proper metal handling practice is extremely vital for obtaining high quality sand casting.

With appropriate foundry technique employ, to cast a complex casting with varying wall thickness will not be a problem. Choong Fei is proud to be able to achieve this with our 46-years experiences and expertise in the sand casting industry.

3. GRAVITY CASTING

Gravity die casting is used to manufacture casting parts from non-ferrous materials such as aluminium or low-temperature alloys. The process is used to create intricately shaped components for a wide range of industrial applications in the defence, medical and energy sectors. It involves pouring molten metal, under the force of gravity, into a pre-formed cast iron block which is fully machined to produce the die.

What is the advantages of Gravity Casting:

  • Good dimensional accuracy
  • Smoother cast surface finish than sand casting
  • Improved mechanical properties compared to sand casting
  • Thinner walls can be cast compared to sand casting
  • Reverse draft internal pockets and forms can be cast in using preformed sand core inserts
  • Steel pins and inserts can be cast into the part
