Production process of glass fiber reinforced plastic mould

1. Accept the task book of FRP mold

　　The task book for forming FRP parts is usually proposed by the part designer, and the content is as follows:

　　1). Formal drawing of the finished product after review and signing, and indicate the brand and technical parameters of the product used.

　　2). Manual or technical requirements for FRP parts.

　　3). Production output.

　　4). Samples of FRP parts.

Usually the mold design task book is proposed by the glass fiber reinforced plastic parts craftsman according to the task book of the formed glass fiber reinforced plastic parts, and the mold designer designs the mold on the basis of the formed glass fiber reinforced plastic part task book and the mold design task book.

2. Collect, analyze, and digest the original data of FRP molds

　　 Collect and organize relevant parts design, molding process, molding equipment, mechanical processing and special processing data for use when designing molds.

　　 1). Digest the drawings of FRP parts, understand the purpose of the parts, and analyze the technical requirements such as the manufacturability and dimensional accuracy of the FRP parts. For example, what are the requirements of FRP parts in terms of appearance, color transparency, and performance, whether the geometric structure, slope, and inserts of FRP parts are reasonable, the allowable degree of welding marks, shrinkage and other forming defects, and whether they are coated or not. Post-processing such as assembly, electroplating, bonding, and drilling. Select the size of the plastic parts with extremely high dimensional accuracy for analysis, and see if the estimated molding tolerance is lower than the tolerance of the FRP parts, and whether the FRP parts that meet the requirements can be formed. In addition, it is necessary to understand the curing and molding process parameters of FRP products.

　　2). Digest the process data, analyze whether the molding method, equipment model, material specification, mold structure type and other requirements proposed in the process specification are appropriate and whether they can be implemented.

The molding material should meet the strength requirements of FRP parts, and have good fluidity, uniformity, isotropy, and thermal stability. According to the purpose of FRP parts, the molding material should meet the requirements of dyeing, metal plating, decorative properties, necessary elasticity and plasticity, transparency or opposite reflection properties, adhesiveness or weldability.
