Professional China bucket tooth pin design and production supplier said even through the manufacturing strength for coated sand casting technique is high enough, but its hardened speed is very slowly, so its final coated sand hardened feature would cant normal adapted or match with the general eight word shape standard testing sample.

Professional China bucket tooth pin design and production supplier indicate the slowly hardened speed would lead to the central part for section surface cant be fully harden but harmless influence the correct testing effect, but if consumers has extend the total harden time to ensure the section surface core is fully harden, but due to the final strength value has beyond the limited range for strength instrument, so the testing China bucket tooth pin sample would cant breakage off or the final testing data would cant maintain correct.

So during the shoot manufacturing test sample, professional China bucket tooth pin production supplier would use two semi core box to good fixed one thin steel plate, but divided the standard testing sample into two samples within eleven point two millimeters thickness.
