PROFILE DESIGN & DIE
 
Every success extrusion begins with good design practices. With our years of experiences and exposure to various industries application, Selaco is in a good position to assist the customer to design a profile that suit their needs.

Here are a few tips on good-design practices:
  • Consider the right shape configuration that best suit your functional need. Extrusion are basically classified into solid, hollow and semi-hollow shapes.

  • Specify the most appropriate metal thickness and keep it as uniform as possible. Remember to keep sufficient thickness to avoid risking distortion or damage.

  • Select the correct tolerance on critical or important dimension. The Customer may choose from any international standard such as ANSI H35.2, BS 1474 or JIS H4100 for specification.

  • Choose the right alloy and temper to meet the require strength, machine ability, surface finish and etc.

Beside having good design practice in profile, a successful extrusion requires a well fabricated die too. Selaco is capable of fabricating complete extrusion die with full range of in-house facilities. Latest CAD/CAM technology with machining center are used to fabricate high complexities die. Equipped with fluidised-bed heat treatment facilities. Selaco is able to fabricate new customised die in a short lead time and produce FA sample for customer to fabricate the prototype.
