In the pharmaceutical industry,do you want to ensure that every box of pre-packaged medicine is complete, intact and compliant before leaving the factory?

In the food industry,are you facing strict requirements on net content such as the German Pre-Packaging Act?

In the non-food, chemical, mechanical manufacturing or logistics industries,do you want to improve process efficiency, reduce errors and create more added value with the help of weight monitoring?

Intelligent Checkweighing Systems——Ensuring products on the production line meet net weight requirements.

The SameGram intelligent checkweighing system combines high precision with high throughput. Suitable for a wide range of industrial applications, it helps ensure that products on the production line comply with net weight requirements, reduces waste, and safeguards brand reputation across sectors such as food, packaging, cosmetics, chemicals, and logistics.Precise weighing is not only key to regulatory compliance but also a core method for optimizing processes, minimizing waste, and guaranteeing product quality—making it an indispensable component of quality assurance systems in modern manufacturing.

Quality Assurance in the Food Industry

In food production, weight control is not only related to production costs, but also directly affects consumer safety and brand reputation. In particular, under the premise of complying with strict regulations such as the European Food Safety Act (Regulation (EC) No 852/2004), manufacturers must avoid overfilling or underfilling. SameGram's dynamic checkweighing system can accurately weigh each package to ensure the quality and consistency of each product, while reducing waste and cost increases caused by improper packaging.

In addition, food production requires not only weight detection, but also the prevention of foreign objects from entering the package. Our automatic checkweigher system can be seamlessly integrated with additional modules such as metal detectors to ensure that foreign metal objects in the package are detected and removed in time, in accordance with EU food safety standards, ensuring consumer safety. If you want to ensure the consistency of quality of each product and comply with food safety regulations, and can also perfectly integrate with the original production line, then our SCF series food checkweigher is your best choice.

Underweighting does not save costs, while overweighting increases costs

In the cosmetics industry, raw materials are often expensive, so it is particularly important to ensure the accurate packaging of each product. Underweighting not only does not save costs, but may cause consumers to distrust the brand, which in turn affects sales and reputation. Overweighting means wasting precious raw materials, increasing unnecessary production costs, and reducing overall profits. Especially in the cosmetics industry, accurate weight control is crucial to the brand, because every drop of raw material waste may have a significant impact on costs.

SameGram's high-speed checweigher can effectively avoid overfilling or underfilling through high-precision weight detection, ensuring that each package meets strict weight standards and minimizes raw material waste. Combined with metal detectors and visual inspection modules, the cosmetic checkweigher system can also detect potential foreign body contamination in real time to ensure that every bottle of cosmetics meets hygiene and safety requirements. We help cosmetics manufacturers improve production efficiency, reduce raw material waste, and improve product quality and brand image, so that consumers can enjoy high-quality products while also getting a safe and reliable use experience.

Q: How much space is required to install a checkweigher?
The required space for installing in-motion checkweighers depends on product size, conveyor speed, and rejector type. Proper planning ensures smooth integration and future maintenance access.
A:
In-motion checkweighers installations typically require space for the checkweigher scale, conveyor infeed/outfeed, and reject mechanism. Most standard units fit into existing lines with minimal modifications. For accurate setup, refer to the checkweigher manual, which includes dimensions, safety zones, and service access guidelines. Our team provides checkweigher service and onsite checkweigher training to assist with layout planning. Proper spacing ensures accurate check weigh operations and simplifies future maintenance. Custom configurations are available for limited spaces or complex layouts. Contact us for a tailored installation plan based on your product and production environment.
Q: How do checkweighers reject non-compliant products?
A checkweigher reject system within checkweighing and rejection systems uses automated mechanisms—air jets, pushers, swing gates, or drop belts—to instantly remove off-spec products on the conveyor.
A:

In modern automated inspection and rejection systems, every product is weighed on an in-line checkweigher as it travels. Once weight falls outside the set tolerance, the checkweigher reject system engages. Lightweight items are diverted with a pneumatic rejection system (air jet), while heavier ones may be pushed off by actuated arms or gates. Fragile or sticky items drop gently via flaps or belts. This conveyor-based inspection and rejection system ensures real-time quality control, maintaining flow speed and minimizing product loss—a vital feature of contemporary conveyor reject system implementations.
Q: Do I need to calibrate the checkweigher regularly?
Yes, regular checkweigher calibration is essential to maintain accuracy, reduce error rates, and ensure compliance with quality standards, especially for hi-speed or high-performance checkweighers.
A:
Regular checkweigher calibration ensures your system maintains precise performance and operates within acceptable checkweigher tolerance limits. Over time, environmental changes, mechanical wear, and product variation can affect accuracy. Following a standard checkweigher calibration procedure—which includes placing certified test weights on the conveyor and adjusting the system accordingly—is critical for consistent results. For a hi-speed checkweigher or high performance checkweigher, calibration should be more frequent due to tighter tolerances and faster throughput. Proper calibration not only prevents overfill/underfill issues but also supports audits and traceability in regulated industries. We recommend weekly or monthly calibration, depending on your production intensity and compliance needs.
Q: What certifications and quality standards does SameGram comply with?
SameGram machines comply with international certifications like ISO, CE, and FDA, and meet food safety audit standards such as BRC and IFS.
A:
SameGram equipment is manufactured to meet international quality and safety standards, ensuring reliability in global markets. Our machines are designed in compliance with ISO-certified manufacturing practices and meet the food safety requirements of GFSI, BRC, and IFS audits. Many models are also built with CE-marked components and FDA-compliant materials for contact surfaces, making them suitable for the food, beverage, and pharmaceutical industries. This commitment to compliance ensures that SameGram systems can be seamlessly integrated into regulated production environments.
