It's possible to shorten the product development schedule! Why not challenge yourself to reduce lead times and costs with molds?
This document introduces the "hard iron plating treatment for aluminum alloy molds for injection molding" by Japan Platech Co., Ltd. By applying a thin film of hard iron plating to aluminum alloy molds, it is possible to shorten product development schedules and reduce injection molding cycle times. This allows for shorter delivery times for molds and lower costs. If you already have aluminum alloy molds, it is also possible to apply plating treatment to them. Please feel free to consult us. 【Contents】 ■ Would you like to challenge shortening delivery times and reducing costs with molds? ■ Surface treatment using hard iron plating on aluminum alloys ■ Features of aluminum alloy molds for injection molding with hard iron plating ■ Molding tests using aluminum alloy molds with hard iron plating ■ Comparison of aluminum alloy molds and steel molds through cooling analysis *For more details, please refer to the PDF document or feel free to contact us.

![[Precision Mold Design and Parts Processing Case] Punching of Fiber Materials](https://image.www.ipros.com/public/product/image/35c/2000593612/IPROS15646106155092654825.png?w=280&h=280)
Design and manufacturing are possible with a clearance of 0.003mm! Processing of new materials such as thin foil and high-strength fibers is also possible.
A consultation was received from an automotive parts manufacturer, stating that they could not punch out fiber materials with molds from other companies, resulting in poor productivity, and they wanted to process with their own molds. In response, we proposed a minimal clearance of 0.003mm and improvements in mold structure and component accuracy. As a result, we were able to punch out the Vectran fiber material (t=0.05mm) due to the difference in clearance. [Case Overview] ■ Customer Industry: Automotive Parts Manufacturer ■ Consultation Content: Unable to punch out fiber materials with molds from other companies ■ Proposed Solution: Minimal clearance of 0.003mm ■ Technology Used: Improvements in mold structure and component accuracy *For more details, please refer to the PDF document or feel free to contact us.
![Press molds [Precision mold design and parts processing examples] Reduction of product burrs](https://image.www.ipros.com/public/product/image/578/2000593614/IPROS00702503970914089870.png?w=280&h=280)
Eliminate burrs through mold manufacturing that meets the product requirements sought by customers! Introducing a case study from an electronic components manufacturer.
When extracting thin products, it is necessary to set a significantly narrow punch-die clearance, but it is difficult to reliably achieve the set clearance in tolerance design. However, our company designs components from the design stage to realize narrow clearances, so we can custom-manufacture both fabricated and purchased parts. As a result, we can produce molds that meet the required specifications for the products our customers seek. 【Case Overview】 ■ Customer Industry: Electronic Component Manufacturer ■ Consultation Content: Desire to cut thin products sharply ■ Proposed Solution: Ultra-narrow clearance punching mold ■ Technology Used: Improvement of mold structure and component precision ■ Outcome: Eliminated previously unresolved punching burrs *For more details, please refer to the PDF document or feel free to contact us.
