In today's rapidly developing market environment, the tableware industry is facing increasingly stringent requirements on product performance and quality. Ningbo Changya, relying on its profound technical accumulation in the field of polypropylene (PP) materials, is committed to improving the performance of disposable PP tableware to meet the diverse needs of customers. Through a series of material improvements and production process optimization, Ningbo Changya has successfully achieved significant performance improvements in PP tableware.
Material improvement: improving the mechanical properties of PP materials
PP is the core material of Changya disposable tableware, and its mechanical properties are directly related to the durability of the product. Changya's R&D team has adopted a variety of innovative material improvement technologies to significantly enhance the strength, stiffness and toughness of PP materials.
First of all, the application of glass fiber reinforcement technology has significantly improved the flexural strength and compressive strength of PP materials. By evenly dispersing the glass fibers in the PP matrix, the reinforced material exhibits excellent shape stability during long-term use, effectively preventing deformation and breakage of tableware.
Secondly, the introduction of mineral filling modification technology, using mineral fillers such as talc and calcium carbonate, further improves the hardness and wear resistance of tableware. These mineral fillers not only optimize the internal structure of the material, but also help reduce production costs, making Changya's Disposable PP Cutlery more competitive in the market while ensuring high quality.
In addition, Changya also uses nanocomposite technology to significantly improve the strength, hardness, wear resistance and heat resistance of the material by introducing nanoparticles such as inorganic substances and metal oxides into the PP material. The tableware made of this nano-composite PP material not only excels in durability, but also maintains stable performance in high temperature environments and can adapt to a variety of usage scenarios.

Production process optimization: improving overall product performance
On the basis of material improvement, Changya has further improved the durability and overall performance of Disposable PP Cutlery by optimizing the production process.
The application of high-precision molds ensures the dimensional accuracy and shape stability of tableware during the injection molding process. By optimizing the mold structure, Changya can effectively reduce the stress concentration generated during the injection molding process, thereby improving the impact resistance and durability of the tableware.
In terms of injection molding process control, Changya precisely controls key parameters such as temperature, pressure and time to ensure that the PP material is fully melted and evenly distributed during the injection molding process. This refined process control not only improves the mechanical properties of tableware, but also ensures the consistency and reliability of the product.
Finally, Changya implements a series of post-processing processes after injection molding, including annealing and surface treatment. These post-processing processes effectively eliminate the internal stress generated during the injection molding process, further improve the surface hardness and wear resistance of the tableware, and enhance the product's aesthetics and market competitiveness.
