1 Scope

This section GB/T 27797 specifies the general principle of injection molding bulk molding compound (BMC) of the test sample is given by the repeatability

Injection molding conditions the same mold design details of the type of sample. Where appropriate, this part of GB/T 27797 also apply to sheet molding

Plastics (SMC) for injection molding. Its purpose is to enhance the main parameters of the injection molding process consistency, establish a unified operating conditions in the injection report

Make regulations. Under special conditions, for comparing the experimental injection of test panels, we need to change the use of the injection material. These conditions should be in the appropriate injection material

The standard method is given, or the two sides reach an agreement.

Note. The test showed that the mold design is an important factor repeated injection of the sample.

GB/T 27797 in this part of the GB/T 27797.1 used together.
