Our systems help businesses like yours achieve automated weight inspection, boost efficiency, and ensure product safety and compliance. Explore how checkweighers can transform your operations below.
What is a In-Motion Checkweigher?
A checkweigher is an automated machine designed to verify the weight of products during the manufacturing process, ensuring they meet predefined design specifications and regulatory standards. In factories, especially in food production, in-motion checkweighers play a critical role in quality control by detecting underweight or overweight items, preventing non-compliant products from reaching consumers. This not only safeguards brand reputation but also minimizes waste and legal risks.
At SameGram, our High-Precision and Ultra-Fast Checkweigher series exemplifies this technology. Certified to MID and ISO standards, these systems offer accuracy from ±0.05g to ±30g and speeds up to 180 pieces per minute, making them ideal for high-volume lines. Whether you're dealing with food packaging or pharmaceutical dosing, our checkweighers ensure every product conforms to norms like FDA regulations or EU directives.
Key Applications of Inline Checkweighers
Inline checkweighers are versatile tools applied across industries to solve real-world problems like inconsistent product weights, regulatory non-compliance, and production inefficiencies. Here's a detailed look at their applications, drawing from proven industry practices:
Food Industry Applications
In food manufacturing, food industry checkweighers ensure packaged products match label weights, reducing giveaway (overfilling) and preventing underfilling fines. They integrate into lines for raw materials, packaging, labeling, and sorting.
● Bakery & Confectionery: Weighing bread, pastries, and sweets to maintain portion consistency.
● Dairy, Meat & Poultry: Checking cheese blocks, yogurt, or poultry trays for accurate weights.
● Prepared Meals & Snacks: Verifying frozen meals, bagged salads, or chip bags to comply with average weight systems.
● Beverages & Sauces: Inspecting bottles, cans, or jars for correct fill levels.
For instance, in a food processing factory, our SameGram food safety checkweighers have helped clients like Panpan Foods achieve 99.8% accuracy, cutting labor costs by 40% through automated rejection and data logging.
Pharmaceutical Industry Applications
Precision is paramount in pharma to ensure dosage accuracy and patient safety. Checkweighers handle sampling, capsules, tablets, and more.
● Capsules & Tablets: 100% weighing with accuracy to detect under- or overfilled items.
● Individual Packaging (Sticks/Sachets): Compact inspection for space-saving on multi-lane lines.
● Small-Diameter Bottles & Aerosol Inhalers: Stable transfer and weighing for eye drops or inhalers.
● Multi-Lane Inspection: Centralized control for high-speed lines, compliant with CFR 21 Part 11 for data security.
SameGram's modular checkweighers support pharma needs with hygienic stainless steel designs, easy cleaning, and integration with metal detectors for contaminant-free production.
Other Industry Applications of Motion Checkweigher
Motion checkweighers extend beyond food and pharma, providing essential weight verification in diverse sectors to address challenges like product variability, compliance with packaging regulations, and operational efficiency. SameGram's robust systems, with capacities up to 80kg and industrial-grade durability, are tailored for these environments, offering features like stainless steel construction for harsh conditions and real-time data integration.
Cosmetics & Personal Care
In the beauty industry, checkweighers ensure precise filling of products to meet consumer expectations and regulatory standards, preventing underfilled items that could lead to complaints or recalls. Examples include weighing perfumes, lotions, shampoos, and creams in bottles or jars; inspecting stick packs or sachets for multi-track high-speed lines; verifying eye lotions, nasal drops, or compact cosmetics with high accuracy (±0.5g or better); and end-of-line checks for personal care items like soaps or deodorants to comply with weight labeling laws. Our SameGram checkweighers have enabled cosmetics manufacturers to achieve 99% compliance rates, reducing waste by automating rejection of non-conforming packages.
