One of the key drivers of the Singapore economy, the manufacturing industry contributes about 20 to 25 per cent of its Gross Domestic Product (GDP). Precision Engineering (PE) - the backbone of the industry - is applied in sectors from aerospace to medical, equipment building to oil & gas. From simple contract manufacturing in the early days, the Singapore precision engineering sector now provides integrated solutions from design to prototyping to production and even supply chain management. The sector recorded a growth of about four per cent in 2014.
