Our machinery capability covers high volume nickel, cobalt, titanium, and high temperature strength based raw materials like as Inconel, A286, Stellite, Udimet, Waspalloy etc.

Acceptance Quality Limit (AQL) at HSF:

In-House AQL Control Based on ANSI/ASQC Z1.4 & ANSI/ASQC Z1.9

Independence & International Standards & Customer Approvals

Our business discipline is based on fully independent control and validation of all processes and tolerances based on international standards and customer requirements. Our First piece and FAI approvals are standard practice triggered by our stringent contract review process. If the contract has any revisions or corrections arising from client or our side, we always require client confirmation on the revision. Client confirmation and approval is main and only approval condition for the contracts. This is all documented through our quality management system and ERP that are tailored to fit our customer’s shipping documentation and quality record requirements and certifications.
Our quality control laboratory can with fully independent quality and process approval discipline apply the Non-Destructive and Destructive Testing procedures. In-house and external all stage approvals are managed with AQL limits by quality control laboratory.
