Key Mold Design & Technical Advantages
1. 1×1 Single Cavity Structure for Precision Control
The single-cavity design eliminates cavity-to-cavity variation, ensuring every scale body maintains identical dimensions, wall thickness, and surface quality. This is critical for the structural integrity and aesthetic consistency of weighing scale housings, where fit and finish directly impact product quality.
2. Dual Steel Combination: LKM738H Core/Cavity + P20 Mold Base
LKM738H Core & Cavity: This pre-hardened steel offers excellent toughness, wear resistance, and polishability. It is ideal for ABS molding, resisting cavity wear and deformation even in long production runs.
P20 Mold Base: Provides a stable, cost-effective foundation with good machinability and strength, supporting the core/cavity while reducing overall mold cost.
This combination balances performance and cost, delivering long mold life without unnecessary over-investment.
3. Dual Surface Treatment: Polished + Etched Texture
The mold features a combination of polished and etched surfaces to meet the scale body’s functional and aesthetic needs:
Polished Areas: Produce smooth, glossy sections (e.g., display window frames, top surfaces) for a clean, premium appearance.
Etched Texture Areas: Create non-slip, matte or patterned surfaces (e.g., side panels, bottom sections) that hide fingerprints and minor scratches, improving user experience.
The mold is engineered to reproduce these textures consistently across every shot.
4. ABS-Optimized Molding Performance
The mold’s design is tailored for ABS material, which offers good impact resistance and dimensional stability for scale housings:
Optimized cooling channels to minimize warpage, a common issue with large ABS parts.
Balanced gate placement to ensure uniform melt flow, preventing sink marks or flow lines on visible surfaces.
Robust ejection system to handle the rigid scale body without deformation during demolding.

FAQ
Q1: Why use LKM738H for the core and cavity instead of just P20?
A1: LKM738H offers superior toughness, wear resistance, and polishability compared to standard P20. This is critical for maintaining the fine etched texture and polished finish over many cycles, especially with large ABS parts.
Q2: Can the mold produce different texture patterns for different scale models?
A2: Yes. The etched texture is customizable based on your design requirements. We can modify the texture pattern or add new features as needed for different scale body variants.
Q3: How long is the expected service life of this mold?
A3: With proper maintenance, the LKM738H core/cavity and P20 base combination can support 300,000–500,000 shots for ABS scale bodies, maintaining consistent quality throughout its lifespan.
Q4: Does the mold address warpage issues common with large ABS parts?
A4: Yes. The mold is designed with optimized cooling channels and balanced gating to control melt flow and cooling rates, significantly reducing the risk of warpage in the large scale body.
