Technical requirements for top cover plate of washing machine

Common substrates: ABS, melamine board, ink glass fast positioning,

Hard requirements

excellent high and low temperature performance
without flashing , high waterproofing
and high final strength ,
good colloid strength and thermal stability

Operational requirements

after curing , otherwise the wire drawing will affect the production
of stable glue, no bubbles, continuous glue
odor will greatly affect the comfort of workers.
When the track is short, air conditioning or fan should be installed in the workshop to speed up whitening
