No need for processing steps for cast test pieces! 'Shell mold' for cast tensile tests.
Simple No. 8 test piece shell mold
Are you not performing "machining" for the production of tensile strength test specimens? A shell mold for cast iron tensile tests that can significantly reduce the process and cost of machining round bars for quality testing.
The production of tensile strength test specimens (No. 8 test specimens for castings FC) has traditionally required both casting with a test specimen mold and machining processes. However, with our shell mold, the shape of the mold itself is equivalent to JIS standards, eliminating the need for machining processes! 【Do you have any of these concerns?】 ■ Due to the processes of casting and machining, we cannot shorten the delivery time any further… ■ We are negotiating prices, but honestly, there are no areas where we can cut costs… ■ Due to a shortage of manpower, we want to minimize labor and reduce manufacturing hours… The 'Simple No. 8 Test Specimen Shell Mold' developed by our company can solve these issues, as it is a shell mold with a central part of 20mm, aligned with JIS standards! ★ Free samples of the test specimen mold are currently available ★ ⇒ If you would like a sample, please let us know by indicating "Request for Free Sample" in the contact form below. * For more details, please refer to the PDF document or feel free to contact us.

basic information
【About Quality Assurance】 We have received a research report stating that we requested the Heavy Industry Research Institute to conduct a comparative tensile strength test, and it was demonstrated that "for FC150 and FC200, the simple casting products (our simple No. 8 test piece shell molds) achieve tensile strength equivalent to that requiring machining, and can be used as a quality assurance test on site." (February 2010) 【About Lot Numbers】 We can accommodate a wide range of lot sizes, from a minimum of 1 piece to units of 1,000. *For more details, please refer to the PDF materials or feel free to contact us.

Detailed information
-
Tensile test results of shell molds show the tensile strength of molten metal inoculated with materials FC150, FC200, and FC250. The tensile strength of simple cast products and round bar processed products yielded almost the same results, indicating that the simple cast products are sufficient for manufacturing site management.
-
Tensile test specimen after fracture Top: Simple type Bottom: Round bar processed type
-
Appearance of the product immediately after pouring. To prevent leakage, the bonding surfaces of the product were glued with adhesive and further secured with a band to fix the mold. The time until demolding was set to one hour from the pouring.
