What Are the Parting Principles for Complex GRC Shapes? Qinglong GRC Mold Parting Technical Guide

Parting of complex GRC shapes must follow six principles: 1) Place parting lines on visually secondary surfaces; 2) Avoid overly small acute angles (<30°); 3) Ensure smooth demolding (draft angle ≥1°); 4) Facilitate mold machining; 5) Favor component installation; 6) Control the number of joints. Through scientific parting, the visual effect is ensured while reducing mold difficulty and production costs.

Specific application case: For a relief sculpture, optimized parting consolidated the original design from 12 pieces into 8, reducing joints by 30% and improving overall integrity. The parting lines were cleverly set at internal corners, nearly invisible to the eye. Qinglong GRC determined the optimal parting scheme through parametric analysis, achieving a unity of artistry and economy.

Aesthetic Parting Principles

Parting lines avoid visually damaging zones and are placed on visually secondary surfaces. They follow the flow of the shape to maintain integrity. Joint width is controlled to harmonize with the whole. Viewing distance is considered; joints may be appropriately widened for long-distance viewing.

Process Parting Requirements

Draft angle ≥1°, ≥2° for special shapes. Avoid undercut structures; use loose pieces where truly necessary. Ensure sufficient mold strength to prevent deformation. Machining processes must be feasible with controllable costs.

Installation Parting Considerations

Single-piece weight ≤200kg for ease of installation. Dimensions suitable for transport, avoiding oversize limits. Connection points positioned sensibly to ensure safety. Installation sequence clearly defined to avoid interference.

Economic Parting Optimization

Reduce the number of molds to lower costs. Improve material utilization and reduce waste. Optimize production processes to increase efficiency. Standardize part of the molds to enable reuse.
