How to choose suitable electronic scale mold materials
The core of selecting electronic scale mold materials is to match product requirements, mold lifespan, and cost budget, taking into account the material, accuracy requirements, and production batch of electronic scale components.
The core of selecting electronic scale mold materials is to match product requirements, mold lifespan, and cost budget, taking into account the material, accuracy requirements, and production batch of electronic scale components.
1、 Core selection criteria
The selection of electronic scale molds should revolve around the following three key dimensions, which directly determine the choice of materials.
1. Product material and characteristics
If the product is made of ordinary plastics such as ABS, PP, etc., it has less wear on the mold and can choose materials with higher cost-effectiveness.
If the product contains glass fiber and mineral filling (to enhance strength), it will aggravate mold wear, and high hardness and high wear resistance materials should be selected.
2. Mold accuracy and surface requirements
The external components such as panels and shells of electronic scales usually require high gloss and no weld marks, and materials with good polishing performance should be selected.
The sensor mounting base, internal structural components, and other functional parts require high dimensional accuracy and require materials with good stability and processing precision.
3. Production batch and mold life
Small batch production (below 10000 level): Prioritize cost and choose pre hardened steel to meet demand.
Large scale production (above 100000 level): It is necessary to balance wear resistance and fatigue resistance, and quenched and tempered steel or cold work die steel should be selected.
2、 Selection Decision Process
Following the following three steps can quickly lock in suitable mold materials.
1. Clarify the core requirements of the product
Determine the material (including fillers), surface quality (high gloss/matte), and dimensional accuracy level of the electronic scale components.
2. Evaluate production scale
Based on the expected annual production, determine the required lifespan level of the mold to avoid cost waste caused by excessive material selection.
3. Balance performance and cost
Small batch, ordinary parts: Prioritize pre hardened steel (such as 718H) to reduce processing and material costs.
Large batch, high-precision parts: choose quenched steel (such as S136) to ensure long-term stable production of molds and reduce maintenance costs
