Rapid-Iteration Extension Springs with No-Mold Cost for Prototype & Low Volume
1.Tension Spring Quick Detail
We understand that time is of the essence. Tingfeng Hardware is committed to becoming one of the fastest-responding precision tension spring suppliers in the market. We have integrated a full range of high-speed manufacturing resources from Φ0.1mm to Φ12mm wire diameters and established a simplified and efficient project process. Whether your needs are urgent samples or sudden production surge orders, we can respond within a very short cycle (48 hours for samples, 72 hours for trial production) thanks to our mature process database and flexible scheduling system. Backed by a powerful production capacity of 500,000 pieces/day, we ensure that your project schedule will never be delayed due to supply chain issues.
2.Tension Spring Product Description
In fast-paced product development, a spring supplier capable of rapid iteration and precise implementation is crucial. We offer precisely this "agile manufacturing" capability. Once you provide your concept or drawings, our engineering team quickly conducts a feasibility assessment and provides manufacturability recommendations. We possess a large library of common hook-shaped molds, allowing many designs to be produced directly without mold creation, significantly reducing lead time. For mass production, we employ modular production units and standardized operating procedures, ensuring consistent quality while enabling rapid order changeover and delivery. Choosing us means gaining valuable time for your project.

5.Tension Spring Product Application
To cope with a rapidly changing market, we need faster springs: Consumer electronics product iterations: Springs for opening and closing new TWS earphone charging cases and camera reset springs for mobile phone pop-ups require suppliers to keep up with rapid ID design changes and market launches.
Promotional items and seasonal products: Springs for moving parts in holiday decorations and springs for toy launch mechanisms require suppliers to handle short-term order surges and rapid delivery.
R&D and prototyping stages: Prototype production in university labs and R&D centers requires extremely low minimum order quantities and extremely fast sample delivery to validate design concepts.
Aftermarket repair market: Urgently needed replacement springs for car door handles and tension springs for appliance door seals require suppliers to have stock or be able to rapidly produce small batches of replacement parts.
