In fields such as biological experimentation and medical testing, petri dishes serve as core fundamental consumables. Quality requirements including their flatness and uniform wall thickness are all guaranteed by high-quality petri dish molds. The precision, materials and craftsmanship of molds directly determine consumable quality, production efficiency and cost control.
In fields such as biological experimentation and medical testing, petri dishes serve as core fundamental consumables. Quality requirements including their flatness and uniform wall thickness are all guaranteed by high-quality petri dish molds. The precision, materials and craftsmanship of molds directly determine consumable quality, production efficiency and cost control.
Manufactured with CNC precision machining, the diameter error is ≤±0.1mm, and the wall thickness uniformity error is ≤0.05mm, fully complying with industry standards. The mold cavity undergoes multiple polishing processes, resulting in a smooth and impurity-free surface. This ensures experimental accuracy and supports the production of petri dishes in various standard and customized specifications.
Crafted from high-quality alloy steels such as P20 and H13, and processed through professional heat treatment, the mold achieves a hardness of HRC 45-50, enabling it to withstand high-temperature sterilization and raw material friction. The mold cavity surface is treated with nitriding and chrome plating, enhancing demolding performance and corrosion resistance. Its service life exceeds 1 million cycles, far surpassing that of ordinary molds.
The pouring and cooling systems are optimized, with a single-mold molding cycle of only 10-15 seconds. Adopting an efficient demolding mechanism combining ejector pins and air ejection, the demolding success rate exceeds 99.9%. It is compatible with automated production lines, significantly improving efficiency and reducing labor costs.
In response to the personalized needs of different scenarios, including biopharmaceuticals, CDC (Centers for Disease Control and Prevention), and research institutions, we provide a full-process customization service covering design, mold development and mass production. We precisely match core requirements such as raw materials, dimensions and craftsmanship, helping customers build competitive advantages in segmented markets.
