Speed is always key for success. An advantage of only one day could change the world. We always support the players who would try to get ahead of existing framework to win in the market. Kimura Foundry America serves the highest quality castings in as little as 5 business days after receiving data from the customer. This speed would create time to verify the best geometry of the component from the variations in design leading to the best performance and cost.
During the prototyping process in various industries, engineers in the R&D section try to optimize the function and efficiency of the component. Such trials could end up with broken part of the component in the middle of test run. Kimura Foundry America delivers the part with the earliest possible timeframe so that engineers can restart the activity without long suspension of the test runs.
<Our typical process from quotation to shipment>
Day 0: Kimura sends back a quotation within 24 hours after receiving inquiry.
Day 1: Customer sends a purchase order and data to Kimura. Kimura summarizes customer requirement.
Day 2: Kimura runs MAGMA simulation multiple times for optimizing casting plan.
Kimura imports the data to 3D sand printer and 3D sand printer starts running.
Finished sand mold (core) is taken out from the 3D printer and cleaned.
Day 3: Sand mold (and core) is set into flask and molten metal is poured.
Day 4: Cast product is taken out from flask for finishing.
Day 5: Inspection and packing. Ready to ship.
Pattern making is always time consuming and generates additional cost. When the number of products is limited, the best way is skipping pattern making. When you check the old pattern in your storage and find it is no longer usable due to wear or bad maintenance, how do you feel? We offer to store your product design by 3D data so that you can receive the part on time. We keep your design in our data storage and create sand molds and cores directly from the data for producing casting parts in 5 days. You don’t need to worry about the condition of the pattern any more. Producing casting from 3D printed sand mold/core is the fastest and smartest solution. Our process is ideal for the project customized a profile of the component depends on the conditions or requirements by the circumstances or clients and replace the part in several years. You will have higher customer satisfaction with more variety of components and less idle time caused by unavailability of spare parts.
Once you complete pattern making, it becomes difficult and costly to make modifications. However, with KFA’s process you can expand the time to optimize the design until the last minutes before you freeze the design. We support every engineer who never compromises the design work to realize a better future.
Kimura Foundry America is always trying to solve the problems of casting. A long history as foundry and very high simulation capabilities enable us to directly focus on the problem and solve typical quality issues of castings like porosity, gas defect, shrinkage, blowhole, etc. Within the simulation software we are able to use the optimization feature to create an efficient design based on our criteria. We guarantee a defect free parts every time because we run through several times of simulation before deciding a casting design.
Quality Casting Supply to Agricultural Machinery Component in 1.5 week
Solution: Very Short Delivery Lead Time of Quality Casting
A customer who manufactures the components assembled to agricultural machinery (Customer A) faced serious quality problem on one of casting parts for their production. Customer A immediately focused on the issue and started discussion with the foundry. The foundry tried to improve the pouring process, however the first trial was not good enough to eliminate the quality problem.
Customer A contacted Kimura Foundry America in 2019 and received the quotation of the part with the 1.5 weeks delivery lead time. Customer A decided to order 20 pieces of the part from Kimura Foundry America.
Customer A and the foundry could have enough time to focus on the problem and succeeded to eliminate the issue completely during the time the foundry could hold the production and focus on the issue.
Customer A shared the information of quality problem at the regular foundry and Kimura Foundry America run the MAGMA simulation X times to optimize the casting plan. Following day Kimura Foundry America start production and completed 20 pcs production in 5 business days. 1st casting part was CT scanned at Kimura and confirmed as defect free condition.
- Customer shared the information about defect precisely to Kimura Foundry – America, who could directly focus on the problem.
- Kimura Foundry America used powerful simulation software to identify the best casting plan within a couple of hours.
Optimization of Design on the Automotive Component in the prototype stage
Solution: Simultaneous production with various designs
Customer B is manufacturing automotive components and one of global leading companies. In particular project, the designer team lead a couple of designs of the component before evaluating final design. The team decided to run functional test with 3 different designs and ordered 2 pieces of each design to Kimura Foundry America.
Kimura Foundry America run the simulation with different design respectively and confirmed the casting plan of each design. Sand 3D printer start printing sand mold and core in the same job box of the printer and all printing work had been completed same time in the following day.
Customer B received all prototype parts with 3 different design at the same time 2 weeks after purchase order was released.
- Sand 3D printer can create sand mold (and core) with different design at the same time. This technology is good to determine the best design out of several choices in the limited time frame.
