V. Attention Points

Beyond the key considerations in plastic cup mould manufacturing, attention points that could be either beneficial or detrimental also play vital roles. They are typically comprised of three major aspects which are the mould, the process, and the personnel.

Within the mold attention points that must be considered include

 Mould Maintenance: The maintenance aspect of the mould activates the cleaning, lubrication, inspection, and repair routines that if not attended to, can present as a setback in the shelf cycle of the mould.

Alignment and Assembly: TDL pays attention to the detailing of the plastic cup’s mould alignment and assembly. The opposite of this is a misalignment in the mould’s assembly will result in product defects that no manufacturer expects. On top of that production cost skyrockets.

Now attention points that pertain to the process include

Process Optimization: TDL does no joke with every step of the mould manufacturing stage, hence the constant inspection and monitoring of the process. To be honest, monitoring begins from the alignment of the mold during assembly and it continues even into the production process. With that, the process is optimized allowing for less production cycle, minimizing material waste, and above all enhanced efficiency and productivity.

Concerning Personnel TDL ensures its workforce continuously undergoes several training and development programs, all geared to equipping them with efficient and cost-saving production techniques.

Preventing Cup Sticking

VI. Preventing Sticking Issues

Plastic cup mould manufacturing presents various hurdles to overcome before achieving perfection, one such hurdle is sticky situations commonly referred to as sticking challenges. However, for a top leading manufacturer such as TDL, the assignment of preventing these sticky situations is well understood and mitigated. That is why TDL adopts innovative ways of preventing cups from sticking up to the mould’s cavity during the moulding process. To achieve this, TDL employs a well-calculated method that entails designing and incorporating vents that improve air supply within the mould. That’s one way to counter the effect of sticking issues. Another way is by the application of release agents into the mould. This helps the mould experience less friction, thus allowing the seamless removal of the component from the mould after the moulding process.

TDL takes it up another notch by applying polishing mechanisms to eliminate sticking issues. It is found that a rough component surface may trap air within the plastic cup mould.
