Why do many bosses choose electronic scale molds
Bosses tend to choose electronic scale molds for production, mainly due to various factors such as the demand characteristics of the electronic scale market, the technological advantages of the molds themselves, and production efficiency. The following are its core characteristics and selection logic:
Bosses tend to choose electronic scale molds for production, mainly due to various factors such as the demand characteristics of the electronic scale market, the technological advantages of the molds themselves, and production efficiency. The following are its core characteristics and selection logic:
1、 Adapt to the precision requirements of electronic scale products
As a measuring tool, electronic scales require high structural accuracy and stability, and electronic scale molds can meet these characteristics:
High dimensional accuracy: The shell, sensor mounting slot, display screen fitting position and other components of the electronic scale need to be strictly matched. The mold is processed with high precision (such as CNC milling, EDM) to ensure that the dimensional tolerance of the parts is controlled within ± 0.01~0.05mm, avoiding measurement errors or structural looseness caused by assembly clearances.
Excellent surface quality: The shell of electronic scales often needs to have the characteristics of scratch resistance and easy cleaning. After polishing the mold cavity (mirror accuracy can reach Ra0.02~0.05 μ m), the surface of injection molded parts is smooth and flawless, without the need for additional polishing, reducing subsequent processing costs.
Structural complexity adaptation: Modern electronic scales integrate display screens, buttons, sensor modules, etc., with complex internal structures (such as buckles, ribs, positioning columns). The electronic scale mold can be designed with multiple cavities, sliders, sloping tops, etc., forming complex structures in one go, reducing component splicing, and improving overall stability.
2、 Production efficiency and cost advantages
Strong mass production capability: Electronic scales are standardized mass-produced products, and the molds are usually designed with multiple cavities (such as 1 out 2, 1 out 4), combined with high-speed injection molding machines. Multiple parts can be produced in a single cycle, and the daily production capacity can reach thousands to tens of thousands of pieces, meeting the large-scale market demand.
High material utilization rate: Optimize the flow channel layout (such as hot runner system) during mold design to reduce plastic melt waste. At the same time, the consistency of part size is high, and the scrap rate can be controlled below 1%, reducing raw material costs.
Long service life and low maintenance cost: Electronic scale molds are mostly made of high-strength mold steels such as S136 and 718H. After quenching and nitriding treatment, the surface hardness can reach HRC50~55, and the service life can reach 500000~1 million molds, with low long-term cost sharing.
3、 Adapt to diverse product designs
Compatible with multiple materials: The shell of the electronic scale may be made of different plastics such as ABS, PC, PP (even metal powder injection molding), and the electronic scale mold can be adjusted by adjusting the temperature and pressure parameters of the mold cavity to adapt to the flowability and shrinkage rate of different materials, meeting the performance requirements of temperature resistance, impact resistance, etc. of the product.
Rapid response design iteration: The market's demand for the appearance (such as ultra-thin, curved design) and functionality (such as Bluetooth, waterproof) of electronic scales iterates quickly, and the mold can be quickly modified through modular design (such as replacing cavity inserts) without the need to re mold, shortening the product launch cycle.
4、 Adapt to automated production
Electronic scale molds are easy to integrate into automated production lines:
The mold can reserve interfaces such as ejector holes and positioning pins, which can be used in conjunction with a robotic arm to achieve automatic part extraction and water outlet, reducing manual intervention.
Some molds are equipped with built-in sensors that monitor the pressure and temperature of the mold cavity in real time, and provide feedback data through the MES system to achieve intelligent control of the production process and ensure product consistency.
