Shall we reduce costs and lighten the load?

Shall we reduce costs and lighten the load?

Implementing integrated production in-house! We manufacture various forged products according to customer needs.

When comparing the material weight and scrap weight of products machined from round bars versus those machined from forged products, there is a significant difference in the amount of processing required, even if the finished products weigh the same. By incorporating the forging process, substantial cost reductions in both material and processing costs can be achieved. Additionally, by utilizing the flow of the internal structure of the metal, forged flow lines that conform to the shape can be obtained, allowing for the production of strong products and enabling weight reduction. 【Features】 ■ Cost reduction ■ Short delivery times ■ Small lot production *For more details, please refer to the PDF document or feel free to contact us.

Center holes manufactured by forging! Achieving a production capacity of 40,000 pieces per month.

Center holes manufactured by forging! Achieving a production capacity of 40,000 pieces per month.

Center holes manufactured by forging! Achieving a production capacity of 40,000 pieces per month.

▼Issues - Warm forged products with a center hole shape. - It's a sudden request, but I would like you to respond. - Cannot request manufacturers without a track record of producing constant velocity joints (we have a track record). - A production capacity of 40,000 pieces/month is required. ▼Solutions - Proposed forming the center hole through forging. - Manufactured using hot forging, shaping the center hole at the tip of the shaft and inside the cup. Reduced machining processes. - Other companies attempted but could not achieve it, and it was evaluated as groundbreaking. - Quickly set up equipment in response to the sudden request, achieving a production capacity of 40,000 pieces/month. ▼Specifications Material: S55C Weight: 2.1kg Dimensions: Φ92.5×169.8mm Accuracy: -0.5 to +1.5mm Equipment: 1600-ton forging press Quantity: 1,000 to 40,000 pieces/month ▼Molds We handle everything from mold design to mold manufacturing and maintenance in-house. Not only do we produce forged products, but we also undertake mold design, ensuring product accuracy. Tokyo Precision Forging Co., Ltd. 1858 Osawa, Joso City, Ibaraki Prefecture, 300-2727 TEL: 0297-42-4631 FAX: 0297-42-4634

By bending and shaping with a vending machine, mold costs are reduced by 20%!

By bending and shaping with a vending machine, mold costs are reduced by 20%!

By bending and shaping the workpiece with a vending machine, mold costs are reduced by 20%!

▼Issues - We want to bend the workpiece without cutting the flow lines to maintain the strength of the product. - Normally, molds are used to bend the workpiece, but this increases the size and cost of the product. ▼Solutions - By using a bending machine to bend the workpiece, we can reduce mold costs by 20%. - We adjusted the shape of the central pivot, the length of the workpiece to be bent, and the angle, allowing the bending machine to be used in the forging bending process. ▼Specifications Material: MCB240H Weight: 6.45 kg Dimensions: 80 × 220 × 260 mm Accuracy: -0.5 to +1.5 mm Equipment: 3-ton air stamp hammer Quantity: 1 to 200 pieces/month ▼Molds We handle everything from mold design to mold manufacturing and maintenance in-house. Not only can we produce forged products, but we can also take on mold design, ensuring the accuracy of the products.

Tokyo Precision Forging Co., Ltd. Company Profile

Tokyo Precision Forging Co., Ltd. Company Profile

We will think of the best solutions together and do our best! We will provide products that satisfy our customers.

Since its establishment over 80 years ago, Tokyo Seimitsu Forging Co., Ltd. has been manufacturing a wide variety of forged products, including automotive parts, construction machinery parts, and industrial machinery parts. In addition to hot forging equipment such as hot forging presses and air stamp hammers, we also possess cold forging equipment. As a result, we are capable of producing composite forged products that combine hot forging and cold forging. Utilizing our extensive experience and technology, along with the newly introduced 3D forging simulation system, we provide products that satisfy our customers. Our company is actively engaged in "reducing CO2 emissions" and has introduced solar power generation equipment in 2023, which covers about 20% of the electricity used in our factory through self-generated power. Additionally, we have contracted for "CO2-free electricity" for the remaining power usage, achieving carbon neutrality (zero CO2 emissions). *For more details, please refer to the PDF document or feel free to contact us.

Proposal for a 30% reduction in mold costs and a 25% reduction in product costs.

Proposal for a 30% reduction in mold costs and a 25% reduction in product costs.

Complex shape manufacturing through hot forging! Achieving short delivery times with a consistent production system from mold design to shipping.

Our company is committed to improving our technical capabilities by introducing advanced forging simulation, responding to our customers' needs. We have forging equipment including forging presses ranging from 1000 to 3150 tons and air stamp hammers of 1.5 tons and 3 tons, enabling the production of forged products in various shapes and sizes. Primarily, hot forged products are manufactured using die forging. While die forging may have a reputation for being costly in small quantities, we keep costs down by reducing material costs and setup time. 【Features】 ■ Improved yield through closed forging ■ Increased productivity through multiple parts production with presses and hammer forging ■ Processing-free through combined forging of "hot forging + cold forging" *For more details, please refer to the PDF document or feel free to contact us.

25% reduction in product costs by using hot forging for mass production and inserting molds!

25% reduction in product costs by using hot forging for mass production and inserting molds!

By using hot forging for mass production and converting the mold to an insert type, product costs are reduced by 25%!

▼Issues - We want to manufacture a large number of small products. - We want to keep costs low. ▼Solutions - Since the products are small and the quantity is large, we used a mold that produces 6 pieces at a time. Even with a lower yield, productivity improved by 17%. - We converted the mold to an insert type, reducing the material cost of the mold by 17%. - By only performing hole drilling after forging, we were able to use it as a finished part, reducing the product cost per piece by 25%. ▼Specifications Material: S25C (Steel) Weight: 0.2kg Dimensions: 24 × 51 × 24 mm Accuracy: -0.5 to +1.5mm Equipment: 1.5-ton air stamp hammer Quantity: 3,000 to 15,000 pieces/month ▼Molds We handle everything from mold design to mold manufacturing and maintenance in-house. Not only do we produce forged products, but we also take on mold design, allowing us to maintain product accuracy.

Achieving weight reduction by forging eight closely spaced holes without deformation!!

Achieving weight reduction by forging eight closely spaced holes without deformation!!

Achieving weight reduction by forging eight closely spaced holes without deformation!!

▼Issues - It is necessary to create lightweight holes (Φ20mm x 8 holes) in the inner diameter of the gear. - Due to the thick wall and narrow spacing between the holes, deformation is likely to occur when drilling the holes. ▼Solutions - By clamping the product with a die during molding, we prevented deformation during hole punching. - Simultaneously punching the outer burrs improved production by 10%. - Normally, when punching 8 holes, the material in the gear section deforms and warps, but we solved this issue by innovating the previous process. ▼Specifications Material: SCR420H (steel) Weight: 3kg Dimensions: Φ130 x 148mm Accuracy: -0.5 to +1.5mm Equipment: 2500-ton forging press Quantity: 500 to 16,000 pieces/month ▼Mold We handle everything from mold design to mold production and maintenance in-house. Not only do we manufacture forged products, but we also take on mold design, ensuring product accuracy.
