Confirmation subjects of trial manufacture | "DIE ENGINEERING"

1.Conﬁrmation of mold installation

No	Conﬁrmation subject	Content
1-1	Conﬁrmation of valve PL surface	PL surface of valve is higher than PL surface of mold about 0.03～0.04.
1-2	Hit on Bunryukoʼs sleeve	Performance is good.

2.Conﬁrmation before production

No	Conﬁrmation subject	Content
2-1	Lubricant spray spot and time	Please make sure piston and valve of ﬁxed side is sprayed more than 1sec.
2-2	Vacuum suction line	Please make sure hose is connected ﬁrmly.
2-3	Valve protection air line	Please make sure valve protection air is supplied during low and high speed die casting.

3.Conﬁrmation during production

No	Conﬁrmation subject	Content
3-1	Valve protection air	During low speed ・high speed die casting valve protection air should be supplied. After intensified pressure signal is accept, this function stop supplying air. Note：If this function is ON by manual operation, it cannot stop automatically.
3-2	Burning state of chip lubricant	During molten metal fill , whether lubricant burning is much or not（Smoke is little）.
3-3	Clearance of valve	Whether there is clearance between valve PL surface. （Please check whether there is burring or not）.
3-4	Valve action	When mold is opened, valve is opened at the same time. Note：If valve opens a little slower, the possibility of clogging risk is high.
3-5	Vacuum suction action	Whether you can see white gas inside hose running （Reference：During vacuum suction, vacuum hose is shrink a little ）.
3-6	Vacuum suction timing	Whether vacuum suction action is earlier than injection sound can be heard.

4.Appearance

No	Conﬁrmation subject	Content
4-1	Appearance of valve exhaust groove
4-2	Appearance conﬁrmation（Whole）	Inﬂuence of vacuum suction can be checked

5.Others
