This is a technical proposal example for the production of driven gears. In the case of the product mentioned here, the conventional method required component strength, so after machining with S45C material, heat treatment was performed to achieve the necessary strength. However, due to the product's weight (300g), there were challenges regarding the cost of heat treatment. Therefore, we proposed a method transition to "780 high-tensile material" combined with precision shearing processing. This allowed us to manufacture a product that previously took three days in just a few hours, achieving a 40% cost reduction as a result. [Case Overview] ■ Before Proposal: Ensured strength through heat treatment ■ Effect: 40% cost reduction by eliminating heat treatment through material change to "780 high-tensile material" *For more details, please refer to the related links or feel free to contact us.

This is a technical proposal example for the production of luggage gears. In this case, the product was initially considered for gear production using hob machining. However, hob machining posed a problem of high costs due to the impact of takt time and material costs. Therefore, we proposed a method transition from traditional hob machining to transfer press processing. This achieved a 30% cost reduction and a 50% reduction in lead time. [Case Overview] ■ Issue: Material costs are high with hob machining ■ Effect: Transitioning to progressive press processing resulted in a 30% cost reduction *For more details, please refer to the related links or feel free to contact us.

This is a technical proposal case for the production of seatbelt components. The products in this case were traditionally produced using fine blanking. As they are related parts for automotive seatbelts, they were manufactured in various locations around the world. However, fluctuations in exchange rates significantly affected prices, leading to the challenge of wanting to reduce costs. Therefore, we proposed a method transition to general press processing using cold forging and precision shearing. This achieved a 30% cost reduction while maintaining the same level of precision as fine blanking. [Case Summary] ■ Before Proposal: Produced using fine blanking ■ Effect: 30% cost reduction through method transition to general press *For more details, please refer to the related links or feel free to contact us.

This is a technical proposal example for the production of sheet frames. The product in this case was initially designed with machining drawings and was planned to be manufactured through machining. The expected monthly production was 2,000 to 3,000 units, but there was a challenge that production through cutting processes would result in high costs. Therefore, we proposed a method transition from cutting to press processing through cold forging. This led to a 40% reduction in costs. [Case Overview] ■Challenge: High costs with cutting processes ■Effect: 40% cost reduction through method transition to press processing *For more details, please refer to the related links or feel free to contact us.

This is a case study of a technical proposal for sim ring manufacturing. Due to the customer's request to reduce procurement costs since product processing is outsourced, we received an inquiry about whether it was possible to maintain the same quality as fine blanking products while processing them with a press. In response, we proposed a method that combines cold forging and precision shearing press technology. By converting fine blanking to general press processing, we achieved a 40% cost reduction. [Case Overview] ■ Challenge: To achieve cost reduction while maintaining quality ■ Effect: 40% cost reduction through conversion to general press processing *For more details, please refer to the related links or feel free to contact us.

This is a technical proposal example for the production of color frames. In conventional methods, the processing of parts before welding and the welding work required significant man-hours and lead time, along with strict requirements for product dimensions and precision, which led to challenges such as prolonged lead times and high costs. We proposed a shift from a method that involved welding multiple parts to an integrated processing method using progressive stamping and cold forging. This achieved a 30% cost reduction and a 50% reduction in lead time. [Case Overview] ■ Challenge: Production through welding of multiple parts ■ Proposal: Integration of multiple parts through a shift to progressive stamping *For more details, please refer to the related links or feel free to contact us.

This is a technical proposal example for the production of strikers. In this case, the product was traditionally manufactured using a single press process involving 10 steps. There was a need to produce 3,000 units per month, but there was a problem with a low yield rate, and additionally, the labor and lead time required for the 10 steps of single press processing made the production very labor-intensive. By switching from the 10-step single press process to progressive press processing combined with machining, we achieved a 40% cost reduction and a 70% reduction in lead time. [Case Overview] ■ Issue: We want to reduce labor and lead time. ■ Effect: By converting from single press processing to progressive press processing, we achieved a 70% reduction in lead time. *For more details, please refer to the related links or feel free to contact us.

This is a case study of a technical proposal for the production of polished processed products. In this case, the product was traditionally produced by polishing both sides after press production. Since the thickness was outside the tolerance range with just regular press processing, double-sided polishing was necessary to guarantee the thickness, but this posed challenges due to the labor involved and high costs. By using re-rolled material for press processing, we eliminated the need for polishing, resulting in a 30% cost reduction. [Case Overview] ■Challenge: Is it possible to perform press processing with precision that eliminates the need for polishing? ■Effect: Transitioning to press processing of re-rolled material with managed thickness resulted in a 30% cost reduction. *For more details, please refer to the related links or feel free to contact us.

This is a case study of a technical proposal that transitioned from cutting processing to press processing. In this case, the product was traditionally produced through cutting processing. Due to an annual lot size of about 5,000 units, there were challenges regarding lead time and processing costs in cutting processing. Given the annual lot quantity of around 5,000 units, we intentionally assumed a single press process and designed the process to eliminate distortion by performing multiple finishing operations on the sides. [Case Overview] ■Challenge: We want to convert approximately 5,000 cutting processed products to press processing. ■Effect: By converting to press processing, we achieved a 40% reduction in lead time and a 30% reduction in costs. *For more details, please refer to the related links or feel free to contact us.

This is a technical proposal example that includes a progressive die with dish-shaped reaming processed by cold forging. In this case, the product underwent dish-shaped reaming at two locations after pressing. However, there were challenges related to the lead time and cutting costs associated with secondary machining. To process the dish-shaped reaming while leaving the pilot holes, there was a concern that the roundness of the holes would be compromised. By adding a finishing process for the holes at the end, mass production was achieved. [Case Overview] ■Challenge: Lead time and cutting costs for secondary machining of dish-shaped reaming after pressing ■Proposal: Progressive die including dish-shaped reaming processed by cold forging *For more details, please refer to the related links or feel free to contact us.

This is a technical proposal case aimed at rationalizing reaming processes for products that underwent reaming finishing after press processing. In this case, the product required precise hole diameters, and reaming finishing was performed after pressing. However, there were challenges related to the lead time and machining costs associated with secondary cutting. By setting an appropriate production lot size based on production performance and regularly maintaining the cutting tools used for finishing the reamed holes, stable mass production was achieved. 【Case Overview】 ■Challenge: Lead time and machining costs associated with reaming finishing after pressing ■Proposal: Progressive die including reaming finishing through precision shearing processing *For more details, please refer to the related links or feel free to contact us.
