Investment Casting

Investment Casting, also known as Lost Wax Casting, is a metal-forming technique, which initiates by using wax moulds to create complex metal structures.

Investment casting is a technique that has been in use for thousands of years. Its earliest recorded use dates back to 2500 BC, to create idols, ornaments and jewellery. In its earliest uses, natural bees wax made the patterns and clay created the moulds. 

Our Focus

We deliver a lost-wax casting, customised engineering solution, within the AS9100 quality standard.


Our process is highly suitable for producing small, lightweight intricate parts.

Customer example

When an incumbent casting supplier was failing to deliver, an engineering solution for a complex aerospace impellor was urgently required. The team at Sylatech were rapid in their response and followed a staged process to address the customer’s demands. 

Our Approach

  • Understand the dynamics and challenging geometry of the part

  • Creation of in-house 3D printed rapid prototypes in wax

  • Development of a custom pouring technique for casting of prototypes

  • Approval of process to achieve stringent NDT requirements, including dye-penetrant testing and x-ray

  • The process from initial contact to samples for assessment took place within four weeks.
