ISBM Mould Steel Guide:
\nP20, 718H & 2316 for Korean Buyers<\/h1>\n

The steel grade selection for an ISBM mould determines cavity life, polishability for optical clarity, resistance to corrosive resins, and the total cost of ownership over a 5\u201315 year production cycle. A wrong steel choice cannot be corrected after the mould is machined \u2014 this guide gives Korean ISBM buyers the material science basis to specify correctly the first time.<\/p>\n

Polishability ratings: A1=mirror\/optical clarity; A2=high-gloss; A3=standard. Cavity life assumes standard PET\/PP production with preventive maintenance \u2014 pharmaceutical-grade sterile environments or rPET with high inorganic filler content reduce life by 30\u201340%.<\/p>\n<\/div>\n
