How is the cause of poor Silicone keypad numbness

In the production process of Silicone keypad, sometimes there will be deformation of Silicone keypad, uneven surface, weight specifications of keys do not meet the standards, these circumstances lead to the feeling of Silicone keypad when pressed is extremely uncomfortable. These are caused by poor Silicone keypad numbness.

General causes of numbness are the following eight points:

. Set exhaust frequency and stroke

1. Too many exhaust times are set when forming

2. Exhaust stroke is too large when forming

Note: Thin Silicone Products are particularly affected

. The mold temperature is too high.

1. The mold temperature set during molding is too high

2. If the mold is not lowered for a long time, the continuous high temperature of the mold will form numbness

. The proportion of vulcanizing agent is too high,

A large number of vulcanizing agents added to rubber lead to the proportion of vulcanizing agent added too high

Note: the prepared rubber material placed too long will affect the fluidity of the rubber material during compression and cause numbness

. Vulcanizing agent added too much.

The glue was inserted into the cavity but was numbed by the addition of too much vulcanizer.

Note: Moving the key slowly can also cause numbness

. The operation method is not correct.

The staff did not operate correctly according to the position and method in the operation of material arrangement, which led to the uneven load and poor feel, thus forming the phenomenon of feel numbness

. The operation speed of the discharge is too slow.

The discharging speed of personnel operation is too slow, resulting in the vulcanization of rubber material has begun when discharging

Note: Thin adhesives are particularly affected

. Machine failure.

Vulcanizing machine failure can not normally lead to mold, pressure slow; This leads to numbness.

. The trip is too short.

The stroke of the silicone button is too short, leading to the poor feel of the button, forming a numb feeling.

Note: in this case it is the mold itself or product design problem.

Conclusion:

Numbness belongs to a bad is very serious, no matter from appearance or function is unqualified, so during the production must be good control of this kind of bad, once appear this kind of question should immediately find reason, analysis of whether the operator's operation method is wrong, or because the problem of setting machine, machine malfunction, or because of material itself, As long as the problem is solved, it will avoid causing bad batch sex and avoid affecting the normal production of the factory.
