In order to let you learn more about our company, please allow me to introduce our company to you in the order of the process:

1、            We mix stearic acid and paraffin wax in accordance with the ratio to make wax pattern, as you know, it is better than polyethylene so that the cost is increasing.

2、            In dipping slurry process, most of the suppliers adopt soluble glass technics in domestic area, but we adopt compound technics or colloidal silica technics. As you know, carbon steel castings will be much smoother with compound technics (compound of soluble glass and colloidal silica technics), this method is so popular with our customers. Using colloidal sillica naturally makes our products a little more expensive than ordinary castings.

3、            In shell making, we adopt automatic air-dry line, which was invented under the guidance of our general manager. The indoor temperature was controlled by air-conditions, keeping the temperature at  24℃±1℃, which can make the castings much more stable, the internal tissues much more well-proportioned.

4、            In shell hardening process, we use aluminium chloride to harden the shell. It can make the shell so hard that it can’t be distorted, at the same time the bug which the casting may have will be decreased. If there are letters or numbers in it, they will be much clearer.

5、            In dewaxing process, about 95% of the casting suppliers adopt the original water-dewaxing technics, but we use the advanced steam-dewaxing technics, of which we are very proud, because it’s invented by ourselves. It can effectively avoid the air-hole and sand-hole, making the casting looked much nicer.

6、            In smelt process, we use middle grade fast-smelt furnace, avoiding the emergence of oxides; in molten steel control part, we use Germany-imported direct spectrometer machine, assuring its quality before the molten steel out of the furnace. During this process we use ERP production and management software to get the feedback information.

7、            In shell-knock out process, we have special machines, which can decrease the hitting and knocking easily made by manual shell knocking out.

8、            In ball-blast process, we have hook-patterned and crawler-patterned ball-blasting machine, with steel shot 0.5-0.8, making the products smooth. Of course, if the customer wants it look much nicer, we would carry out sand-blast treatment.

9、            In heat treatment process, we use electric furnace, and adopt double-temperature control in order to heat the products equally. As a result, the products will have great microstructure.

10、        Our tolerance can reach at the grade of 5-7 according to our country’s tolerance standard.

11、        In machining process, we have four numerical control machines, so we can make further machining if the customers need.

12、        Before package, we have to make anti-corrosive, painting or zinc plating treatment according to different requirements.

13、        About package, we adopt Europe standardized fumigation-free wooden case.

14、        It should be noted that our manager is stepping with the pace of the information age, he invited the professor of Shandong University to create a special production and management software which we call ERP. This software makes every workshop connected with the management class, so that we can control the quality in every process in time, and we can store the information in order to inquire and manage. Only one goal: Quality is our unremitting pursuit!
