Stone crushing machine production lines have two main ways to structure production contracts：

In the production of stone crushing machine production lines, there are primarily two main ways to structure production contracts. Shandong Sanxiang Heavy Machinery, based on its experience over the years, shares the following insights:

1. Large-Scale Contract (Full Package): This method involves the customer entrusting the entire production line to the production company. This comprehensive contract typically includes responsibilities from material storage in hoppers to the final material transfer. It also covers expenses such as machine maintenance, spare part replacement, labor wages, electricity costs, forklift fuel, and workers' living expenses. It is crucial to carefully calculate and document these costs because in a "large package" arrangement, all expenses are borne by the production company. The customer, in this case, only pays the production company based on the actual quantity of material produced, as stipulated in the contract. The customer is not involved in any production-related matters and essentially acts as an investor or financier. This is a classic "hands-off management" approach, where the production company takes on most of the risk, but the potential profits are relatively higher.

2. Small-Scale Contract (Partial Package): This approach is relatively simpler. In a small package arrangement, the customer typically entrusts the production process to the production company, ensuring the smooth operation of the production line remains the responsibility of the customer. The expenses for maintenance, spare part replacement, and other operational costs are borne by the customer. In many cases, the customer also covers workers' meal expenses. In this type of contract, the stone factory owner has indirect involvement in the actual production process. The production company doesn't bear the full risk and, therefore, has a lower level of risk. However, the profit margins, relative to the large package method, tend to be lower.

When Shandong Sanxiang Heavy Machinery facilitates negotiations between both parties, they make an effort to transparently present the advantages and disadvantages of these two production contract methods. The final decision on how to collaborate ultimately rests with the customer and the production company.

In summary, there are two primary approaches: "Large Package," where the customer contracts out the entire production line, and "Small Package," where the customer retains more control over production but entrusts specific processes to the production company. Each method has its own set of advantages and risks, and the choice depends on the preferences and objectives of the parties involved.
