Due in metal-plastic composite members forming process, being connect with metal base 23 when being molded melt 24 (i.e. plastic melt)
When touching, if 23 temperature of metal base is relatively low, the heat transfer between 23 surface of plastic melt and metal base can make and metal base
The surface layer melt of 23 contacts reduces rapidly, and the plastic melt on surface layer is caused to be solidified to form condensate layer rapidly.The presence of condensate layer
Plastic melt can be hindered to be immersed to the micropore of metal base 23, to influence the interface cohesion of plastic melt and metal base 23.
In addition, if 23 temperature of metal base is too low in filling process, plastic melt cooling velocity is uneven, can make plastic melt and Metal Substrate
There are larger stress concentrations for junction between material 23, further influence the interface cohesion of plastic melt and metal base 23.When
When 23 temperature of metal base is higher than the glass transition temperature or fusing point of plastic melt, the surface condensation layer of plastic melt can be thinning or disappears
It loses.In a certain range, with the raising of 23 temperature of metal base, the viscosity of plastic melt gradually reduces, the stream of plastic melt
Dynamic property is improved, and is conducive to the small hole that plastic melt is filled into 23 surface of metal base, ensures the interface cohesion of the two.

It is set to 110 degrees Celsius) it is compared, when the actual temperature of metal base 23 is not up to setting value, heating element 11 continues to add
Heat, when 23 actual temperature of metal base reaches setting value, heating element 11 stops heating；
Step 3, shaping stage；
Using injector 15, melt 24 will be molded by the running gate system that is set in mold, directly in 23 table of metal base
Face forms plastic construction feature.The temperature for being molded melt 24 is 230-270 DEG C, injection pressure 80-110MPa, after the completion of injection
Dwell time 5-10s, cooling time, 20s-30s, ensured that injection molding melt 24 can be well into the micropore knot on 23 surface of metal base
Structure improves the bond strength of plastics and metal surface；
Step 4, cooling stage；
Temperature control master unit 7 controls cooling-water duct 20 and cools down metal base 23, until reach the temperature (70 DEG C) that sets as
Only.Temperature control master unit 7 had not only ensured the signal control of temperature control system itself but also can realize that signal is interactive with injection molding machine 15, ensured forming
Process is smoothed out；
Step 5, product takes out；
Melt 24 is molded after the cooling and solidifying of 23 surface of metal base, integral structure is formed with metal base 23, securely ties
It is combined.
It may be implemented to organically combine metal base 23 and plastics (injection molding melt 24) by this method, without using gluing
Agent avoids actual bodily harm of the pernicious gas of adhesive release to operating personnel.The outer of product is made using metal base 23
Surface can meet wall thickness, intensity and the appearance requirement of product.Plastic production product inner surface can play the heat-insulated effect of damping,
Simultaneously as the easy mobility of injection molding melt 24, moreover it is possible to which product of the production with labyrinths such as screw hole, reinforcing ribs meets
The subsequent assembly demand of product.
