Discover SameGram’s high‑precision checkweighing and weight‑sorting solutions for metal parts, plastics and electronic components
In high-tech manufacturing, precision is critical—especially when handling metal, plastic, and electronic components. As a checkweigher manufacturer, SameGram has long demonstrated how our checkweigher systems ensure that every screw, PCB, connector, battery cell, or injection-molded part meets exact weight specifications.These dynamic systems typically consist of infeed, weighing, and rejection modules, enabling 100% in-motion weight inspection—detecting underweight or overweight items and automatically rejecting non-compliant components.
What’s Being Weighed?
Metal parts: Screws, nuts & bolts, stamped brackets, die‑cast housings, machined shafts, metal shims, bearings
Plastic parts: Injection‑moulded housings, caps & closures, connectors, resin pellets, lightweight containers
Electronic components: PCBs & SMT reels, sensors, batteries, wire harnesses, micro‑motors, LED modules
difficulty
Industry Challenges
Micron‑level tolerances
Variations of ±0.02 g can trigger field failures or warranty claims.
Mixed SKU changeovers
Dozens of part numbers per shift require recipe recall in seconds.
Regulatory traceability
ISO 9001, IATF 16949 & IPC‑A‑610 demand full weight records.
Hidden defects
Missing screws in kits or incomplete PCB solder fill are only evident by weight.
Space‑constrained lines
High‑speed assembly cells leave <1 m for inline QA.
Application Scenarios
Metal parts, plastic components, and electronic elements are widely used across modern manufacturing, where precise weight control is critical. The weight accuracy of items such as screws and nuts, injection-molded parts, PCBs, connectors, and battery cells directly impacts assembly quality, functional reliability, and customer trust. SameGram's checkweigher systems offer powerful dynamic weighing capabilities, integrating functions such as weight inspection, missing-part detection, traceability management, and automatic rejection. These systems are well-suited for the high-precision demands of industries including electronics, automotive, and plastic processing.

Conveyor Checkweigher
- The multifunctional rejection and diverting checkweigher is equipped with three types of rejection devices: pushers, sweepers, and air blasts. Designed specifically for packaging lines where multiple production lines converge, it efficiently saves space while effectively handling the increased inspection load from merged lines, boosting overall production efficiency.
Checkweigher for Small Packages SC1-C-3523L1
- This checkweigher is tailored for small accessory and parts bags, equipped to sort packages based on preset weight thresholds into two directions (left or right), making it ideal for inline inspection of items like toy building blocks or component kits. It ensures high precision and rapid automated sorting, boosting production flow efficiency and quality control—all within a compact footprint.
High-Precision Compact Checkweigher
- This high-precision compact checkweigher is tailored for inline weight inspection of single-bag products, accurately detecting underfills or overfills. Conforming items pass forward while rejects are reversed, enabling fast online sorting. Ideal for high-speed packaging applications, it delivers real-time production trend feedback to upstream filling machines—enhancing packaging accuracy, boosting user satisfaction, and reducing costs
Advanced Weigh Price Labeler SCL-10060L50
- This advanced weigh price labeler generates barcodes and QR codes with adjustable print speeds, integrates seamlessly with MES/ERP systems for automatic price calculation and data syncing, and features built-in template editing for fully customizable labels. Its adjustable printhead height and multiple labeling modes support diverse production lines, while the system automatically adapts product info, printer setup, and label positioning/rotation to accommodate different products and environments.
Weigh Price Labeler SCL-7035L5
- This automatic weighing price labeler combines dynamic weighing, barcode/QR generation, and label printing—perfectly syncing with MES/ERP systems. Featuring customizable templates, adjustable printhead height, and multiple labeling modes, it automatically adapts label position and rotation for different products and lines. Commonly used in logistics, food processing, and real-time weighing-labeling workflows.

Delivering High-Precision Weighing Solutions for the Metal, Plastic, and Electronic Component Industries – The SameGram Story
Plastic Components Manufacturer
Application: Raw Material & Rework Sorting with SC1‑C‑3523L1
“Since installing the SC1‑C‑3523L1 checkweigher, we’ve streamlined our rework flow. The system accurately separates off-spec parts before assembly, reducing manual labor and scrap by 30%—all without slowing down production.”
Key Benefits:
• Real‑time sorting of plastic injection scraps and regrind
• Automated traceability through our MES
• Improved first-pass yield from 92% → 98%
Metal Hardware Manufacturer
Application: Custom-designed high-speed dynamic checkweigher on compact conveyor
“We needed checkweighing for tiny metal components, in a constrained line layout. SameGram built a bespoke, compact checkweigher with a narrow belt and quick tare‑to‑gross switch. The equipment now runs at 200 ppm with ±0.1 g accuracy—exactly what our customers require.”
Key Benefits:
• Ultra-compact size fit into our tight workflow
• High throughput without weight drift
• Precise control: every batch now meets DIN tolerance spec
Injection-molded Components Producer
Application: Multi-function rejection & diversion checkweigher at end-of-line
“Our final QC line now features SameGram’s multifunction checkweigher that weights, rejects, and diverts parts before shipping. It’s reduced outward defects by 95% and has saved us from several potential non-compliance issues with overseas buyers.”
Key Benefits:
• 100% end‑of‑line inspection ensures no short‑shots ship
• Automatic rejection reduces QC manpower by 50%
• Custom diversion paths for non-conforming parts
