Moulds for the Production of FRP Products

A complete, professional FRP mold typically consists of three parts:

1. Mold Surface

Definition: This is the part of the mold that comes into direct contact with the product and serves as the working surface. It directly determines the product's appearance quality (smoothness, texture) and key dimensional accuracy.

2. Mold Structure: The framework that supports the mold surface. It provides sufficient strength and rigidity to prevent deformation or damage during the production process (e.g., vacuum pressure, clamping force).

3. Auxiliary Systems: Devices added to achieve specific functions. They ensure a smooth production process and product quality.

Common Systems:

Demolding System: Such as draft angles, air lifts, and release agents.

Positioning System: Such as locating pins and clamping clamps, which ensure precise alignment of the upper and lower molds.

Heating/Cooling System: Pipes within the metal mold used for temperature control and curing. Sealing System: Sealing grooves and strips used in vacuum infusion or RTM processes.

Injection/Venting System: Resin injection and venting holes used in processes like RTM.

Molds are the bridge between product design creativity and industrial mass production. Investing in a well-designed and expertly crafted mold is a crucial first step in ensuring the success of FRP products in terms of quality, cost, and efficiency. Understanding the concept of molds is fundamental to understanding the entire FRP production process.
