| Surface treatment | Provides multiple options such as nickel plating (corrosion resistance), tin plating (weldability), silver plating (high conductivity), passivation (stainless steel), etc |
| File support | Can accept drawings in formats such as AI, DXF, DWG, STEP, IGES, etc., and provide DFM (manufacturability analysis) reports to collaborate with your engineering team to optimize the design. |
Core strengths
▲Deeply cultivating OEM/ODM manufacturing: We focus on providing professional back-to-back manufacturing services for brand owners and assemblers. Your design, our craftsmanship, seamless integration.
▲Precision stamping technology: using high-speed precision punching machines and multi station progressive die technology to ensure the dimensional accuracy (up to ± 0.01mm), contour consistency, and efficient mass production of the shrapnel.
▲Comprehensive material selection: Processing various metal sheets including phosphor bronze, beryllium copper, stainless steel, spring steel, brass, etc., we can recommend the best materials based on your requirements for conductivity, elasticity, corrosion resistance, and cost.
▲One stop value-added service: not limited to stamping. We provide a full process service from stamping, bending, heat treatment (stress relief, increased elasticity), electroplating (nickel plating, tin plating, silver plating, etc.) to automatic optical inspection, simplifying your supply chain.
▲Rigorous quality control: From raw material incoming inspection to online SPC statistical process control, and then to finished product full inspection/sampling, we ensure that the performance (such as contact force, life cycle) of each batch of products is stable and reliable.
Widely used in fields that require precision elasticity and electrical contact
▲Consumer electronics: phone/laptop battery connection spring, SIM card holder spring, shielding cover contact point.
▲Household appliances: relay contacts, controller interfaces, motor brushes.
▲Automotive electronics: sensor connectors, ECU module contacts, in car entertainment system interfaces.
▲Industrial equipment: industrial control chassis shielding shrapnel, power connectors, heavy-duty connectors, internal contact terminals.
▲Communication equipment: base station filter contact piece, RF module shrapnel.
Our manufacturing process
▲Requirement analysis and DFM: Review your drawings and provide recommendations for manufacturability optimization.
▲Mold design and manufacturing: Use high-precision slow wire/mirror spark machine to manufacture progressive molds, ensuring lifespan and accuracy.
▲Precision stamping: High speed stamping and automatic material collection are carried out in dust-free/temperature controlled workshops.
▲Secondary processing and heat treatment: If necessary, bending, aging treatment, etc. should be carried out to stabilize the elastic properties.
▲Surface treatment: A strictly controlled electroplating process is carried out in a cooperative electroplating factory.
▲Comprehensive quality inspection: Use projectors, salt spray testing machines, mechanical testers, etc. to conduct size, appearance, and functional tests.
▲Packaging and delivery: Anti static/anti rust packaging, delivered on time according to order requirements.
FAQ
Q1: Can you provide samples?
A: Of course you can. After receiving your detailed drawings and requirements, we can quickly produce samples (usually within 5-10 working days) for you to test and verify.
Q2: What is the minimum order quantity (MOQ)?
A: As an OEM manufacturer, our MOQ is flexible. For standard parts, the MOQ can be 10000 pieces; For high complexity customized parts, negotiations can be made based on mold costs.
Q3: How to ensure the consistency and lifespan of shrapnel?
A: We ensure this through high-precision molds, strictly controlled stamping parameters, and standardized heat treatment processes. Each batch will undergo elasticity testing and life sampling, and an inspection report will be provided.
Q4: How long does it take from mold opening to mass production?
A: The typical cycle is: mold manufacturing (15-25 days) ->sample confirmation (5-7 days) ->mass production start-up. The specific time depends on the complexity of the product.
Q5: Do you provide assembly services?
A: Yes, we can assemble the stamped shrapnel with other stamped and injection molded parts to provide a complete submodule.
