True Care Technology TCW-450 and TCW-600 heavy-duty checkweighers verify shipping cases from 0.05 kg to 25 kg at 1 g resolution and up to 40 cases per minute [S1].
The equipment is built for shipper cartons, cases, bags, and drums, using SUS304 stainless steel and a push-off rejector [S1].
Define the Case-Level Weighing Requirement
A case checkweigher measures the complete shipping unit against programmed lower and upper limits before palletising, and it can identify a missing component that would otherwise remain hidden inside the carton [S3][S4].
The scope is distinct from a retail-pack inspection. The True Care machine handles full shipper cartons, sacks, and drums across food, pharmaceutical, cosmetic, chemical, agricultural, FMCG, hardware, and toy applications [S1].
Capacity is only one part of the specification. A 25 kg nominal load can still fail on belt length, belt width, support geometry, airflow, or reject handling, so dimensions and product behaviour must be confirmed with the equipment supplier [S4].
Compare Heavy-Duty and Larger-Capacity Platforms
Two published TCW heavy models cover a 0.05–25 kg weighing range [S1].
The TCW platform is the tighter match when cases remain at or below 25 kg.
Select From Footprint, Capacity, and Throughput
The published TCW-450 configuration has a weighing range of 0.05–25 kg, 1 g resolution, and a throughput of up to 40 pieces per minute [S1].
Match the Reject Method to the Shipping Case
The TCW models use a push-off rejector [S1].
Account for Air, Guarding, and Installation Conditions
These dimensions are installation constraints, not cosmetic preferences. A 25 kg case with a high or shifting center of gravity requires a stable transfer approach and a reject device capable of controlling that load without tipping it [S4].
Control the Tolerance and Protect the Data Trail
Full-case controls accept user-programmed acceptable weight limits, and underweight cases can indicate that an expected product or package is absent [S3].
Set case tolerances against the packed configuration rather than nominal case weight alone. For example, a missing 500 g pack from a 12 kg case creates a 4% shortfall, so the underweight limit must be tight enough to detect that quantity [S4].
These controls allow recipes to be separated from operator access and retain test histories for complaint investigation [S1].
Fit the Checkweigher into the End-of-Line Sequence
Place case weighing after the case is closed and before palletising so that the complete outer pack can be checked against its programmed limits [S1][S3].
The line sequence should permit the checkweigher to reject a case without creating a back-up at the palletiser. The Marco CW150S is presented as a checkweigher for cases [S2].
A project using automated case packing should define the reject response before commissioning. For practical tolerance setting, set carton tolerances for reliable automated case packing addresses the interaction between packaging variation and inspection limits.
Verify the Supplier Specification Before Purchase
True Care publishes a 0.05–25 kg weighing range, 1 g resolution, throughput of up to 40 pcs/min, SUS304 construction, and a push-off rejector for the TCW models [S1].
The evidence supports a 25 kg case checkweigher with 1 g resolution as a defensible configuration when its dimensions, stability, and reject mechanism match the actual load. Confirm the final case footprint, worst-case product distribution, line speed, reject accumulation, electrical supply, air quality, and cleaning requirements before accepting the model.
