How To Start Electronic Weighing Scale Making Business | SkillsAndTech

The electronic weighing scale or digital weighing machine is an essential item. It helps in checking a product’s weight. However, without a weight machine, it is not possible to know the exact mass of anything. The electronic weighing system comprises the basic load cell, suitable signal conditioners, and output recorders/ indicators. And they give both the analog and digital output for further processing.

The trends of weighing scales increase towards higher accuracy and lower-cost production. It will increase the demand of high-performance analog signal processing at a low cost.

Different Usage of Electronic Weighing Scale

There is a wide range of usage of the electronic weighing scale. Some of them are listed below:

• First of all, Tabletop/ Retail scales Weighing scales with platforms for retail stores 30 kg. 5 gm.
• Bench scales Weighing scales for chemical industries, wholesalers, grain merchants, all types of industries 1 ton 10 gm.
• Jewelry scales High precision / low capacity weighing scales for weighing precious metals 500 gm. 0.01 gm.
• Analytical scales High precision / low capacity weighing scales for laboratory application 200 gm. 0.01 gm.

• Digital weighing scale in the healthcare industry.
• Industrial Platform scales High capacity weighing scales for high volume weighing such as metals, industrial raw materials. And they have an industrial output of 5 ton 100 gm.
• Hanging scales Heavy duty weighing scales for field weighing 1 ton 10 gm.
• Finally, weighbridges Heavy-duty weighing and rugged electronic weighing scales for truck weighing at industries, warehouses, and transportation depots. capacity is 60 tons 10 kg. The heavy-duty electronic weighing scales such as industrial platform scales and weighbridges use a 4 load cell bridge technique.

Licenses for Electronic Weighing Scale Manufacturing Business

In starting this business, you must apply for different registrations and licenses from the Govt. authority. However, it is advisable to check your state law.

• First of all, register your business with ROC. This is mandatory.
• Apply for Trade License from the local Municipal Authority.
• Furthermore, apply for MSME Udyog Aadhaar online registration for small and medium unit operation
• In addition, apply for BIS certification for ISI Mark. You must maintain the quality standard IS: 2281/1981

• In this business, you must obtain ‘NOC’ from Pollution Control Board. Firstly, apply for ‘Consent to Establish’ and then apply for ‘Consent to Operate’.
