Bakelite Injection Moulding Machine
Bakelite injection moulding machines are specialized machines used for the mass production of Bakelite, a type of plastic that was popular in the early 20th century. Bakelite is a thermosetting plastic that is made by combining phenol and formaldehyde under heat and pressure.
The Bakelite injection moulding machine works by melting the Bakelite pellets in a heated barrel and injecting the molten plastic into a mould under pressure. The mould is then cooled to allow the plastic to solidify and take on the desired shape. The machine can repeat this process quickly and efficiently to produce large quantities of identical Bakelite parts.

Bakelite injection moulding machine plasticization can be divided into the following factors: backpressure, screw speed, material temperature, etc.
A. Large backpressure can make the molten material wholly plasticized and plasticized evenly. Still, because the temperature is too high, it is easy to make the molten material cured in advance to lose fluidity, and it can not be injected.
B. Small backpressure, insufficient plasticization of molten material, poor fluidity of molten material can not fill the shape. It should be adjusted according to the actual situation of raw materials, the wear of the screw barrel, and the appropriate backpressure.
The molten material can not be plasticized entirely; the smaller the screw speed. The smaller the screw speed, the greater the friction during plasticization. The molten material temperature is too high, curing in advance to produce gas to affect the filling, but also increased wear on the screw barrel corrosion.
A. The material temperature is too high, the melt in the screw shear quickly solidifies so that the screw barrel wear increases, more can not be injected, blocking the nozzle.
B. Material temperature is too low, the melt plasticization is not enough, slow injection, can not fill the cavity, melt traces obvious. The material temperature should generally be controlled between 70 ~ 90 ', such as raw materials. PF-161J material temperature should be between 72 ~ 78 '.
C. Mold filling conditions: injection speed, injection pressure, holding time, injection speed is too fast. The greater the frictional heat generated by the melt and mold, the melt local premature curing, or even scorching, while curing water vapor and gas can not be discharged, resulting in chalky pores or lack of glue. Injection speed is too busy, and it is easy to produce flow marks and melt traces.
A. Injection pressure is too enormous so that the melt is well-formed, has good mechanical properties, but increases the internal stress of plastic parts so that the burr thickens and becomes larger (burr is best penetrated with sunlight).
B. Injection pressure is too small, the product is easy to lack glue, repeated lack of glue is likely to lead to black mold adhesive, the product surface loses luster and becomes white.
The longer the holding time, the greater the weight of the plastic parts, and the tighter the plastic parts. a.
A. The holding time is too long after molding becomes difficult, and the weight of the plastic parts will not increase after the holding time exceeds 25 seconds.
B. The shorter the holding time, the higher the shrinkage rate. The shorter the holding time, the shorter the production cycle and premature demolding.
Conditions: Mold temperature, cooling time.
The higher the mold temperature, the shorter the molding cycle, and the higher the production efficiency. But there are also disadvantages.
A. When the mold temperature is too high, the bakelite powder is easily burnt.
B. Pin holes appear, the molten material filled is rapidly cured, and the gas produced is completely discharged.
C.Produce difficult gas and burn yellow mold.
D.The temperature of the mold that produces defects such as mold agent and whitening is too low.
E. The fluidity of the molten front becomes poor, can not fill the core, the curing of the molten material is not tightly combined, poor mechanical strength and poor gloss.
F. Cooling time remains the same. Easy to bond or produce bubbles when after molding.
Annealing treatment after molding: Natural cooling.
