From Raw Material to Finished Locking Gas Spring \u2014 All In-House<\/h2>\n

How We Manufacture<\/h3>\n

GASTAC operates a 10,000 m\u00b2 manufacturing facility with an annual capacity of 2 million locking gas springs. Vertical integration means every critical step is controlled by our own team, not outsourced.<\/p>\n

Our in-house capabilities cover R&D and tooling, CNC machining of cylinder and rod components, automated welding and tube drawing, controlled nitrogen gas filling, final assembly, and a full testing laboratory for force, leak, fatigue, and salt spray. Finished goods are stored and packed on site for export.<\/p>\n

Production lines and in-house tooling development are managed by our own engineering team, which means custom locking gas spring projects can move from drawing to sample without waiting on external suppliers. Nitrogen purity \u226599.99%, filling pressure 2.5\u20135.0 MPa.<\/p>\n

What We Need From You to Start<\/h3>\n

To start a custom locking gas spring project, please provide: a drawing, sample, or parameter sheet; force (F1), stroke, and mounting dimensions; operating temperature range; mounting angle (vertical or inclined); and estimated annual quantity.<\/p>\n

Prototyping takes 7 to 15 days depending on complexity. Sample approval typically takes 3 to 5 days. Mass production runs 15 to 30 days after deposit and sample approval. Tooling fee policy and refund conditions are confirmed at the quotation stage.<\/p>\n

Sample and Prototype<\/h4>\n\n\n\n
\"Custom<\/td>\n\"Locking<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Not sure which parameters to customize? Use our Technical Support Center<\/a> to measure and calculate the exact force and stroke you need. Accurate data on the first enquiry shortens the prototyping cycle significantly.<\/p>\n

<\/p>\n

Sample Quality Equals Mass Production Quality<\/h2>\n

Three-Stage Inspection Process<\/h3>\n

The biggest sourcing risk is a good sample followed by inconsistent mass production. GASTAC controls this with a documented three-stage inspection process, full batch traceability, and a 24-hour complaint response commitment for every locking gas spring order.<\/p>\n

First Article Inspection runs a full dimensional and force check before every new batch. In-Process Inspection performs scheduled checks during assembly and gas filling. Pre-Shipment Inspection does final force, leak, and appearance checks before packing and shipment.<\/p>\n

Batch Traceability and After-Sales<\/h3>\n

Every locking gas spring can be traced back to raw material batch, production date, and inspection record. If a quality issue arises, we respond within 24 hours. A corrective action report is issued within 3 working days, and defective units are replaced or credited if the issue is confirmed on our side.<\/p>\n
