Are you having trouble with non-destructive testing of machine parts? Sanri Special Steel conducts everything from manufacturing to inspection of machine parts, with a particular focus on the production and inspection of large industrial machine components. In addition to manufacturing services from materials to finishing, we have established our own inspection department, where we perform not only dimensional inspections but also high-precision dimensional inspections using three-dimensional measuring machines, as well as three types of non-destructive testing: ultrasonic testing, magnetic testing, and penetrant testing. Because we carry out the entire manufacturing process consistently, we are well aware of the types of defects that can arise from the product's shape and manufacturing methods, allowing us to conduct targeted inspections. What sets Sanri Special Steel apart is that when inspections are requested alone, typically only the quality of the product is assessed. Therefore, if a defect is found, the report usually ends with where the defect is and its size. However, our company offers comprehensive aftercare. If a defect is found, we analyze the trend of the defects and can propose alternative manufacturing methods or take on the manufacturing request. If you are having trouble with non-destructive testing, please feel free to contact Sanri Special Steel.

This is a case of a product for which we received a consultation stating, "The nut manufactured according to the drawing does not fit into the product." Despite the nut with an outer diameter of φ390 and an inner diameter of M340 being completed as per the drawing, it did not fit into the product, so we conducted an investigation at Sanri Special Steel. The dimensions were processed according to the drawing, but when measured with a three-dimensional measuring machine, distortion was found in the threaded portion of the inner diameter. Such phenomena can often occur with spacers, collars, sleeves, and various other products, not just this nut.

Reverse engineering refers to the process of analyzing the structure of a product by disassembling a machine, observing the operation of a product, or analyzing the behavior of software, in order to investigate specifications such as manufacturing methods, operating principles, design drawings, and source code. (Refer to Wikipedia) In other words, it means creating drawings from existing parts and manufacturing identical parts. "If you want me to create a part without a drawing from the actual item." "The parts we have been sourcing can no longer be produced due to the manufacturer's closure." "I want to remake a part that is old and worn out."

• Calibration and repair

This is a product for which we received consultation regarding the production of a complex-shaped crankshaft. Manufacturing Process: Forging → Heat Treatment Preparation → Rough Machining → Heat Treatment → Delivery Customer's Concerns: - Due to considering deformation during heat treatment, excess material was left, leading to increased processing time and costs. - The deformation during heat treatment varies each time, resulting in frequent machining troubles. Our Proposal: - By manufacturing and attaching a special jig during heat treatment, we can suppress deformation. By implementing the above proposal, we eliminated machining troubles, successfully shortened processing time, and reduced costs, greatly pleasing our customer. Our company can consistently handle everything from product measurement to jig manufacturing in-house, and we have utilized our know-how in heat treatment to solve various heat treatment troubles for different shapes.

This is a metal product approximately 800mm in total length, with a 400mm square (hole φ200) centered on both ends of the shaft section measuring φ150*200mm. This product was originally manufactured by the customer, but due to the very precise quality requirements, it was difficult to meet those standards, leading them to consult with our company. Challenges that made processing difficult: - The material was cast iron. - The tolerance settings were strict. Our proposals: - Change the material to forged steel. - Modify the processing steps. - Use a three-dimensional measuring machine. With the above proposals, we were able to meet the customer's needs. Our company has resolved numerous issues by thinking and proposing solutions to our customers' problems. Additionally, we guarantee product quality through calibrated and managed inspection tools and three-dimensional measuring machines, as well as non-destructive testing (by qualified personnel), in accordance with ISO 9001 quality assurance standards.

"Although I was asked to improve the process, I don't know what to do." "The amount to be removed is large, and it takes a long time to process." "I want to reduce material costs." Are you struggling with these kinds of issues? This time, we have summarized an introduction to upset forging and examples of cost reduction. 【What is Upset Forging?】 It is one of the free forging forming methods, also known as "suekome." Generally, this forging technique involves heating the tip or middle of a material (round bar) and then applying pressure in the axial direction to reduce height while simultaneously increasing cross-sectional area to shape it. 【Advantages】 Reduction in material costs and shortening of processing time. 【Disadvantages】 It may become expensive if there is not a certain minimum lot size. Please feel free to contact us regarding cost reduction considerations with upset forging. We have compiled data on the price difference resulting from changing the process from round bar/free forging to upset forging. We offer a wide range of services including materials, heat treatment, lathe work, machining, polishing, and inspection. We will provide the best proposals tailored to our customers. For all your manufacturing needs, please leave it to Sanri Special Steel Co., Ltd.!

• Forging Machine

In recent years, as technological innovations have rapidly advanced, various breakthroughs in processing methods have been observed daily. " I want to place an order, but I'm unsure which processing method is best." Have you ever had such an experience? This time, we will introduce the differences in processing methods using metal products in the shape of rings as an example. When processing a product with dimensions of φ300×φ200×60: (1) Rolling forging → Lathe processing (2) Free forging → Lathe processing (3) Flame cutting (4) Round bar → Lathe processing (5) Round bar → BTA processing If you had the above options, which production method would you choose? If cost reduction is prioritized, producing via round bar → BTA is optimal. If shortening the delivery time is prioritized, producing via flame cutting is optimal. Thus, the choice of processing method varies depending on dimensions, applications, and delivery times. At our company, we utilize the experience we have cultivated over many years to select the optimal method from numerous options and propose it to our customers. Please feel free to contact us. We offer a wide range of services including materials, heat treatment, lathe work, machining, polishing, and inspection. We will provide the best proposals for our customers.

This is a long stainless steel shaft with a maximum outer diameter of 350mm and a length of 4000mm. This stainless steel product has a structure where the shaft part and the flange part are welded together. It was manufactured and used by the customer, but there were frequent cracks at the welds. Therefore, we received a request to change the design and manufacture it as a single piece from a round bar. However, manufacturing from a round bar incurs higher costs for both materials and processing due to the waste involved. To address this, our company proposed a better processing method by minimizing waste through machining from forged products and selecting cooperating companies that meet customer needs from our diverse range of partner companies, achieving stable quality, cost reduction, and shortened delivery times. Additionally, our inspection department ensures product quality assurance through calibrated and managed inspection tools and three-dimensional measuring machines in accordance with ISO9001 quality assurance, as well as non-destructive testing (by qualified personnel).
