From Plastic Buckets to ThinWall Lunch Boxes – How LiSong’s LargeCapacity Design Covers Multiple Product Lines

2026-05-16

Some manufacturers wonder: LiSong produces machines for plastic buckets (large capacity products), and also high speed thin wall machines for disposable cups and lunch boxes – are these two lines contradictory? In fact, this reflects LiSong’s accumulated expertise in both “large shot volume” and “high speed / high pressure” technologies. Moreover, some of its models achieve good compatibility between the two.

 

 

Specifically, LiSong’s large capacity barrel and strong clamping force design are suitable for products with large projected area and high part weight, such as buckets and stools. Its thin wall series, on the other hand, focus on high speed injection and rapid plasticizing. However, there are intermediate models that, by using a replaceable dedicated screw and an adjustable accumulator, can switch between large shot volume mode and high speed thin wall mode. This allows one machine to produce plastic buckets during one order period and thin wall lunch boxes during another, improving equipment utilization and the factory’s production flexibility.

 

For distributors, this product line layout offers two main benefits: first, it covers a broader customer base – serving both daily use plastic goods factories and disposable food packaging factories; second, it encourages customers to choose the same brand when upgrading equipment, thereby increasing customer loyalty.

 

Furthermore, LiSong does not overhype “all in one” capabilities in its marketing. Instead, it clearly states that each machine model has its most suitable product range, and distributors should recommend the matching model based on the customer’s primary products. This fact based, honest approach makes customers perceive the brand as trustworthy. As one distributor noted, they sometimes proactively tell customers: “If more than 90% of your production is thin wall cups, we recommend our dedicated thin wall machine, not a general purpose high tonnage model.” This kind of honest recommendation builds trust and brings many repeat customers.

 

Summary: LiSong’s product portfolio balances both “large capacity” and “high speed thin wall” directions, with reasonable differentiation achieved through dedicated screws and control systems. Distributors can leverage this to build a professional image of “providing the best solution on demand”, thereby establishing long term reputation in the market.
