Quality Statement
Culture of continuous improvement
“Continuous improvement”, is a mentality that every Sigma employee possesses. The management of Sigma Fasteners creates a climate in which
improvements be suggested by everyone in the organization. Open communication is the condition for recognizing the most important issues and implementing solutions.
Striving for zero faults
In each phase of production of our product, the work must be done right. Inspection of products is based on random tests. Prevention is better than reaction; this is the only approach to achieving zero faults. Quality is guaranteed by ensuring that processes remain within well-defined procedures. When taking orders, specifying work orders and job routers customer specifications and industry standards are taken into account. To a large extent, the training and knowledge of the employees determine the success of the policy of striving for zero faults. Short and longer training courses play a key role in keeping their knowledge and ability up to speed.
Reliable Delivery
Sigma strives to meet the delivery times agreed upon with customers. Sigma’s delivery reliability is measured each week. All employees are contentious of due dates and strive to meet internal and customer deliveries.
