Securing Primary Tooling Rights in Chinese Subcontracting Manufacturing Contracts
Securing primary tooling rights in China requires standalone title contracts, clear steel verification, non-lien waivers, and physical shop-floor audits.
Mechanical Shot Counter
Meaning
Hardware devices attached to industrial moulds provide a physical and non-resettable record of every production cycle completed by the equipment. A mechanical shot counter is a reliable and low-cost tool for auditing the output of a factory without relying on digital sensors or supplier reports. The device is typically triggered by the physical movement of the mould plates, ensuring that a count is only recorded when a part is actually made.
Because these counters are built to be tamper-resistant, they serve as a trusted source of truth for the buyer. They are widely used in the manufacturing of plastic components where the lifespan of the mould is measured in the total number of shots it can perform. By checking the counter during a site visit, an auditor can verify if the factory’s production logs match the physical evidence.
This simple piece of engineering is a fundamental part of the asset management strategy for many international companies sourcing from China.
Mechanical Tracking
Reliability in the measurement of production volume is achieved through a direct physical link between the machine’s operation and the counting mechanism. The mechanical shot counter does not require a power source or a data connection to function, making it immune to electrical failures or signal jamming. It is usually housed in a rugged metal casing that is bolted onto the side of the mould.
Each time the mould closes and opens, a internal lever or plunger is depressed, advancing the number on the dial by one. The simplicity of this design means it can operate for millions of cycles without requiring maintenance itself. For the buyer, this provides a permanent record that cannot be easily altered by the factory staff.
If the counter shows a significantly higher number than the reported production, it is a clear indication of unauthorized use of the tool. This mechanical evidence is often used as the basis for financial claims or the termination of a supplier contract.
Verification Method
Auditors use a standardized process to check and record the data from the counting devices during their regular inspections of the manufacturing facility. The verification of a mechanical shot counter begins with a visual inspection of the device to ensure that the seals are intact and there are no signs of tampering. The auditor then records the current number on the dial and compares it to the last recorded value in their files.
The difference between these two numbers represents the total production since the last visit. This figure is then compared to the supplier’s delivery notes and inventory records for the same period. If there is a large gap, the supplier must provide an explanation, such as wasted parts or testing runs.
The auditor also checks the installation of the counter to ensure it cannot be easily bypassed or removed. This physical check is a powerful deterrent against the “grey market” production of parts using the buyer’s intellectual property.
Tamper Protection
Securing the integrity of the count requires the use of specialized seals and mounting techniques that make it obvious if someone has tried to interfere with the device. A mechanical shot counter is often protected by a wire seal or a branded sticker that must be broken to access the mounting screws or the internal mechanism. These seals are unique to the buyer and are replaced by the auditor after every check.
If a seal is found to be broken, it is treated as a major breach of the supplier agreement. Some advanced counters also include a “one-way” mounting system where the screws can only be turned in the direction of tightening, making it impossible to remove the counter without drilling out the metal. The casing of the counter may also be designed to shatter or change color if it is subjected to high heat or mechanical force.
These features ensure that the data on the counter remains a defensible and accurate record of the tool’s life. The goal is to make the cost and risk of tampering higher than any potential benefit from unauthorized production.
