We provide non-standard stamped parts according to customers’ requirements, such as ultra-thin micro parts, high-precision parts, complicated special-shaped parts, etc.

We can reliably manufacture standard precision stamped components within tolerances of ±0.01 mm to ±0.03 mm. Tolerances of up to ±0.005 mm can be consistently achieved with our ultra-high precision products. Our minimum material thickness for working is 0.05mm. We can produce holes with the smallest diameter of 0.1 mm reliably. The minimum bending edge is 0.3 mm without quality loss.

Geometric tolerances such as flatness, perpendicularity and parallelism are precisely controlled to comply with your drawing requirements. All these capabilities fully meet assembly and fitting requirements for high-end precision components. Our process guarantees reliability in the consistent results of entire production batches.

Precision stamping can be done to the precision of ±0.01 mm; conventional stamping can only be done to the precision of ±0.1 mm. Precision stamping creates burr-free edges with virtually no deformation during the stamping process. These high-quality standards are not reliably achieved by conventional stamping.

High-precision wire-cut dies and insert-type dies are used to achieve better accuracy in precision stamping. These special dies have a much longer useful life than conventional tooling. In the conventional stamping process, common dies are used, and their accuracy potential is limited.

In our process, precision levelling, deburring and flattening are all performed on high-speed stamping presses. These techniques allow for great consistency of parts throughout full production runs. This repeatability is not reliable with standard stamping.

When micro components and precision assemblies require high precision, precision stamping is required. This type of precision is required for automated assembly parts and high-end equipment components. There is no way to meet strict tolerances and mass consistency requirements with standard stamping.

We provide a full range of integrated precision stamping services to meet your needs. We are able to flat stamp, precision bend, deep draw, shallow draw and flange. Hole extruding, tapping, press riveting, curling, chamfering, precision flattening and deburring are also done. Blank forming and single-operation forming by high-speed progressive die.

Secondary machining errors can be reduced, and complex-shaped parts can be formed in one multi-operation. This integrated approach saves time in production and greatly enhances dimensional accuracy. Every step of the process is optimised in order to meet your specific component needs.

Our workshop is equipped with high-speed precision stamping presses with advanced technology. Our pneumatic presses, vertical and horizontal drawing machines and precision levellers are of high accuracy. Automatic feeders and optical inspection equipment guarantee uniformity in production. Other automated equipment is used to assist in our manufacturing processes.

Production by high-speed progressive die is capable of producing tens of thousands of pieces per day. The standard precision stamped parts precision stamping output is 10,000-50,000 pieces per day. Orders of mass-volume are continuously executed for 24 hours and provide stable support. We are able to handle small-batch prototyping projects as well as large-scale mass production projects well.

We can process almost all the common precision hardware materials for various applications. We can produce stainless steel of the following grades: SUS304, SUS301, SUS316 and SUS430. The copper alloys we work with include Brass, Phosphor Bronze, Pure Copper and BeCu. Cold-rolled steel (SPCC) and galvanised steel sheets (SECC/SGCC) are routinely processed. We deal in Aluminium Sheets, Aluminium Alloys, Nickel Strips, Nickel Plated Steel Strips and Spring Steel.

Our engineers provide no cost recommendations for optimal materials for your functional needs. We take into account such properties as conductivity, heat dissipation, elasticity, anti-corrosion, wear resistance, and resistance to high temperatures. Upon request, material certificates and RoHS test reports are provided. Material authenticity and conformance to international standards are guaranteed at all times.

Yes, we’re a specialist in ultra-thin precision sheet stamping for challenging applications. Our minimum working thickness is 0.05mm and is consistently of good quality. Sheets of 0.1 mm, 0.2 mm and 0.3 mm are produced regularly.

Thin material processing poses challenges such as deformation, warpage, and dimensional deviation. These problems are addressed by optimised die clearance and secondary flattening processes. Custom fixture setting and low-speed precision stamping strictly control flatness and distortion. All ultra-thin component batches are consistently and reliably produced in stable mass production.

The material is preferably phosphor bronze, beryllium copper and SUS301 spring stainless steel. They offer high elasticity, wear resistance and outstanding conductive properties. When it is important to have better rust-proof and corrosion-resistant performance, SUS304 is recommended. High-quality spring steel is used for the manufacture of cost-effective general-purpose springs with reliability.

Optimisation of die structure and stamping processes is performed especially for elastic components. This improvement extends the life of spring-back and enhances fatigue resistance in a significant manner. Optimisation is tailored to your specific fatigue-test requirements and test specifications. Special treatment is provided to your components for long-term performance.

Periodic maintenance, cleaning and repair procedures are regularly performed on all production-run moulds.

Comprehensive dimensional inspection of each mold is carried out prior to production. Normal wear and minor damage during mass production is repaired free of charge. All repair costs are covered, so you can expect punctual deliveries. This guarantee means you can rely on your production timetables without any problems related to tools.

Prototyping can be used for all products before mass production. Only after prototype samples have been approved is mass production started. In this way, risks in aspects of dimensions, structure and overall appearance are minimised.

Simple prototypes are supplied free of charge to our customers. Courier costs related to prototype sample shipment arrangements are borne by you. For complex, high-precision and multi-stage deep-drawn parts, there will be a small prototyping fee. This fee is 100% refundable when your mass production order is ready. All prototype quality and specification is guaranteed all the time.

We have a complete quality control system during all manufacturing processes. The verification of incoming material is done based on material certificates. Surface condition and thickness are studied in detail prior to production. Non-conforming stock is promptly turned away from our production process.

First article approval – checks all samples from a production run (full dimensional inspection). Only after approval of the initial sample, mass production begins. Every 2 hours, the in-process patrol samples dimensions, appearance and flatness. Final inspection is done before shipment with respect to appearance, burrs and dimensional tolerances.

Defective parts are 100% screened out before packaging for delivery. Pre-delivery re-inspection double-checks all the parameters before the final shipment process. This results in ZERO Batch Deviation and stable product consistency reliably. Several checkpoints ensure that every stamped part delivered is as per your requirements.
