REMAIN AWARE OF MOULD CONTAMINATION
9 March 2020We are a business with a reputation for supplying many unique and practical products, including the mould reamer. The standard tool is one that is useful for all sorts of mechanical operations. As for ours, we design them specifically for repairing moulds, hence the name. You can use them to rectify any faults in a comprehensive manner.
Something about moulds that people have to be aware of is mould contamination. Deposits on mould exteriors can originate from a myriad of sources. The mould and part design could be such that you require considerably high melt-temperatures to fill the part. If this is the case, the user might discover that some deterioration of their components is occurring. This can result in deposits on the mould's surface.
ACCUMULATING AIR PRESSURE
If you don't vent the mould adequately, the air pressure inside is going to build. It will do this as the cavity fills. As pressure rapidly gathers on a fixed weight of gas, the gas' temperature shall rise greatly. This is a principle of physics. Essentially, this is what happens inside a diesel engine when it ignites the fuel.
Within an injection mould, the pressures can rise to a point where the leading edge of the material catches fire. Normally, this leaves behind a dark deposit within the mould. This is at the last point to fill. In addition, it leaves a burned spot on the moulded part. The venting could be marginal. If it is, the part might not experience a burn. However, decomposition products shall assemble in the mould inside the region of the last section to fill.
