Problem & Solution

Q

The casting material swells the release agent

A

The demolding problem needs to be solved comprehensively from three aspects: mold surface treatment, release agent selection, and curing degree control.

Q

Spontaneous combustion phenomenon appears in thermosetting casting material

A

The core of the poor curing problem is that the chemical reaction conditions do not meet the requirements; it is necessary to precisely control the formulation ratio and curing process parameters.

Q

Impact failure of the product in extremely low-temperature environments

A

In summary, the causes of the 「Impact failure of the product in extremely low-temperature environments」 problem can be attributed to the combined action of multiple factors such as the toughness of the resin dropping sharply at extremely low temperatures and insufficient wall thickness. Solving t...
