Casting Defect Resolution Service - Aluminum Castings
We are struggling with casting defects at the current manufacturer... Our company has a wealth of case studies that address issues with casting defects.
Are you facing increased labor hours and delays in delivery due to quality issues with your current manufacturer, resulting in rework and remanufacturing? We often receive inquiries from clients who want to produce with stable quality and delivery times, but find it difficult to achieve improvements with their current manufacturer. On the other hand, changing suppliers can lead to changes in processes, so we also hear voices saying, 'I want to change, but the costs of molds and the setup time are obstacles that make it hard to take the plunge.' Additionally, we possess five casting processes in-house: sand casting, self-hardening, alkaline phenolic, cold box, and die casting, allowing us to select the optimal method based on quantity, shape, and quality requirements. Furthermore, by utilizing casting simulations to confirm the flow of molten metal and solidification conditions in advance, we aim to reduce the risks of casting defects and rework from the prototype stage. We can consistently handle everything from machining, inspection, to surface treatment after casting, which helps alleviate the burden when changing suppliers. If you are struggling with quality improvements, delivery delays, or switching from your current supplier, please feel free to consult with us. We also offer free technical materials summarizing our know-how on casting defects and quality improvements. Please download them from the link below.

Price information
If you provide us with drawings, sample products, or 3D models, we will offer a free estimate. We can accommodate production starting from one piece, and by manufacturing wooden molds and metal molds in-house, we can reduce initial costs even for small quantities. Since costs vary depending on the manufacturing method, we will also suggest switching from machining to 3D printing. (For reference: switching from machining is cost-effective for orders of 5 or more, and switching from 3D printing is cost-effective for orders of 2 or more.)
