Process Highlights and Technical Advantages :
HIROKI CO., LTD. has accumulated years of practical experience in metal component manufacturing, providing professional stamping services across various industries. With a comprehensive equipment lineup, versatile processing capabilities, and flexible process integration, HIROKI has successfully served multiple precision manufacturing sectors, including hand tools, bicycles, automotive, defense, power tools, and sewing machines. Here are eight key strengths that define our operational excellence :
Complete Multi-Tonnage Press Configuration
HIROKI's facility houses a range of automated presses from 15T to 110T, fully covering processing needs from micro-stamping parts to medium-to-large structural components. Smaller presses (15-20T) are ideal for high-precision micro-parts like springs, terminals, and metal foils. Larger models (60-110T) can handle medium-to-thick steel plates and large structural parts used in automotive brackets, bicycle components, and aerospace structural fasteners. This diverse tonnage range allows HIROKI to flexibly handle a variety of custom orders and seamlessly switch between one-off prototyping and high-volume production, enhancing process flexibility and client satisfaction.
High-Speed Continuous Stamping Support
Our small and medium-tonnage presses are often paired with automated feeding systems and continuous dies, enabling a high-cycle, stable, and low-labor-cost production model. This system is particularly suitable for high-volume continuous parts, such as electrical components and precision hardware. By synchronizing automated feeding with the dies, HIROKI maintains a high production pace while ensuring consistent quality and dimensional accuracy, making us a reliable partner for clients with high-volume delivery demands.
Compound Die Processing Capability
HIROKI excels in using compound die technology, integrating multiple processes—such as punching, embossing, cutting, bending, and shallow drawing—into a single operation. This saves time, increases throughput, and reduces tolerance accumulation. This technology is particularly valuable for products requiring precise structures and aesthetic appeal, such as sewing machine parts, automotive interior components, or tool casings, where multiple processes can be completed with a single die, shortening lead times and lowering manufacturing costs.
Custom Die Design Expertise
We possess in-house die design and manufacturing capabilities, assisting clients from initial drawing evaluation and sample design to final die development. During the early development phase, our technical team can analyze product shape, strength requirements, and forming conditions to design a customized die structure. We also assist with initial sample production and issue resolution, significantly shortening the product development cycle and minimizing the risk of trial-and-error.
Broad Material Compatibility
HIROKI has extensive experience processing a wide range of metal materials. Common materials include:
- Cold-Rolled Steel (SPCC): High formability and processing stability, suitable for general structural parts.
- Stainless Steel (SUS304/SUS430): High corrosion resistance, commonly used in the automotive and electronics industries.
- Aluminum Alloys (5052 / 6061): Lightweight and corrosion-resistant, applied in bicycles and aerospace.
- Galvanized Steel: Provides anti-corrosion properties, suitable for outdoor structures or electrical casings.
- High-Tensile Steel, High Carbon Steel: Used for components requiring high structural strength and safety.
Furthermore, HIROKI can provide recommendations on material thickness, hardness, and elastic modulus to improve product yield and lifespan.
All-in-One Integrated Process
Beyond our core stamping capabilities, HIROKI offers a complete post-processing chain, including:
- Precision Grinding: Improves surface flatness and dimensional consistency.
- Deburring: Enhances safety and product feel.。
- Tapping: Facilitates assembly and component integration.。
- Surface Finishing (Electroplating, Anodizing, Painting, etc.): Improves corrosion resistance and aesthetics.。
- Parts Assembly: Supports the assembly of modular finished products, reducing client inventory and labor costs.
This vertical integration allows clients to complete all processes with a single partner, effectively reducing outsourcing risks and communication costs.
Dimensional Accuracy and Stability Control
For quality assurance, HIROKI uses stroke monitoring and pressure sensors to track variations in real-time during each stamping cycle. By analyzing pressure data and managing die lifespan, we proactively prevent quality anomalies. Coupled with periodic measurements, die maintenance, and automated feeding corrections, HIROKI can maintain product dimensional error within ±0.05mm, meeting the strict requirements of precision parts manufacturing.
Efficient Prototyping-to-Mass Production Transition
Our comprehensive range of presses, from 15T to 110T, allows us to use lower-tonnage machines for initial prototyping and process validation. Once a product is confirmed, we can quickly transition to high-tonnage mass production equipment, drastically shortening the development cycle. This tiered equipment structure ensures a seamless "prototype → pilot run → mass production" workflow, avoiding interruptions or factory transfers that could pose risks and enhancing development efficiency and delivery flexibility.
HIROKI CO., LTD. continues to provide competitive metal component solutions by leveraging its comprehensive press configuration, highly integrated processing capabilities, flexible customization support, and unwavering commitment to precision quality. These eight key strengths not only demonstrate HIROKI's capabilities and dedication but also embody our promise of quality, efficiency, and value in service.
