Why Have We Accept and Establish Aerospace Standards for Our Business Ethic?
Quality
HSF believes that accuracy is of absolute importance in the machining and fabrication of aerospace and aircraft parts, which require the highest level of performance under very high stress conditions during flight.
Traceability
HSF’s extensive level of experience provides clients and strategic partners with our assurance that the high precision parts will meet their precise specifications and performance standards.
Our Main Discipline
At HSF, we deliver the highest quality products and services, and we strive to get it right the first time. We continuously improve our performance and processes to ensure we meet or exceed our customers’ expectations.
Acceptance Quality Limit (AQL) at HSF:
In-House AQL Control
HSF does not interpret the sampling requirements contained herein as allowing defective parts (AQL Levels) to be sold to the customers.
Customer Satisfaction
HSF accepts and applies that all supplied parts must comply with all requirements of the Purchase Order, Applicable Standards, Engineering Drawing and / or product description requirements.
AQL Levels We Have Applied
HSF applies 3 levels for AQL:
Critical Characteristics: 100% Inspection shall be assigned unless otherwise specified.
Major Characteristics: 0.65% AQL Level shall be assigned unless otherwise specified.
Minor Characteristics: 2.5% AQL Level shall be assigned unless otherwise specified.
Quality Control and Process Approval
Independence
Our business discipline is based on fully independent control and validation of all processes and tolerances based on international standards and customer requirements.
International Standards
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.
Customer Approvals
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.
HSF produces expertly designed, high-quality, complex machined components and products. Our investment in training and obtaining the latest approvals and certifications provides you with an exceptional level of service and compliance. Current approval levels include ISO 9001, AS9100 rev D, and ISO-EN 17025 compliant.
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.
One of the most important factors when manufacturing parts for aircraft or related systems is safety. There is no room for human or any foreign object error in the production and assembly of an aircraft. From the smallest interior detail to the plane’s exterior, any flaws or inconsistencies can have devastating effects.
All devices and equipment used in HSF production and quality control processes are periodically calibrated, and all calibration records are kept in the ERP system. Policies that prevent the participation of uncalibrated devices or equipment in the production and quality control processes have been developed and are actively implemented.
IN-HOUSE QUALITY CONTROL CAPABILITIES (designed according as ISO-EN 17025 & AS9003A) (updated on 23.02.2024)
All test and measuring devices including the hand tools are periodically calibrated and reported.
