For the casting process improvement, quality of
research, technology improvement for in-depth discussions, January 13, China
Casting Association, and vice director Zhu Jianxun Ying Yuchai invited,
dedicated to Yuchai machine stock company casting factory to carry out academic
exchanges. Yuchai casting expert Tong Siyi, Yuchai casting foundry, member of
the College of professional and technical personnel who participated in the
exchange activities.
Zhu Jianxun focuses on explaining the resin from the
hard sand, cold core box resin sand, the hot core box resin sand the three kinds
of resin sand raw material selection and formulation and blending process, such
as professional and technical knowledge. He pointed out that the resin sand is
which is widely used in sand casting molding and core making materials,
especially cold core box resin sand, resin self hardening sand core making
process modeling simple, type, the core scale accurate, easy to realize
mechanization and automation of production. When it comes to casting paint, Zhu
Jianxun briefly explains the role, composition, properties and preparation
process of coatings. Zhu Jianxun also describes the types, general riser casting
riser feeding principle knowledge.
Experts in exchange meeting, Zhu Jianxun, child Siyi
etc. that Yuchai foundry in new technology and new technology development
rapidly, especially in Vermicular Cast Iron theory research and melting process
has made a series of progress, the degree of mechanization is increasing, they
said in the future to normal and jade Chai casting plant to carry out academic
exchanges and seminars. Zhu Jianxun, child Siyi encouraged foundry workers, to
actively explore the resin sand, sand casting coating, riser and to improve
casting precision grade, the surface quality of the casting, improve casting
working conditions, and increase the rate of finished products and reduce the
production cost and make greater contribution.
After the technical exchange seminar, Zhu Jianxun depth
foundry to observe the foundry production.
