Plastic Mould Steel Plastic Mould Steel Price. Jayant Choosing plastic mold steel is a very important process in mold manufacturing, because the classification of plastic mold are generally on the length of plastic mold by 5 grades, grade1 is over a million times; grade 2 is 500,000-100 million; grade3 is from 300,000 to 500,000; grade4 is from 100,000 to 300,000, grade 5 is 10 million below
Oct 06, 2019 · With regard to the plastic molds for production of transparent plastic parts, the mold cavity and core need to select high-grade imported steel materials that boast an outstanding mirror polishing performance, such as 718 (P20+Ni), NAK80 (P21), S136 (420) and H13 steels, among which, 718 and NAK80 are pre-hardened, so preheat is not necessary

Standard Pre - Hard Mirror Plastic Mould Plate DIN1.2738 718H steel is pre-hard mirror anti-acid plastic mould steel. The steel pre-hardened, uniform material, high cleanliness, excellent polishing performance and lithography. Also has high hardenability, good electrical processing performance and striae processing performance.
P20 mold and 718 mold steel are universal pre-hardened mold steels, which are usually used for large and extra large plastic molds. 718 die steel is equivalent to domestic steel number 3Cr2NiMo. P20 die steel is equivalent to 3Cr2Mo.Compared with P20 mold, 718 die steel adds a small amount of Ni element. From P20 400mm maximum size to 1000mm maximum size, greatly improved Hardenability.
machine tool chatter:Topics by Science.govMay 01, 2018 · An investigation of chatter and tool wear when machining titanium. NASA Technical Reports Server (NTRS) Sutherland, I. A. 1974-01-01. The low thermal conductivity of titanium, together with the low contact area between chip and tool and the unusually high chip velocities, gives rise to high tool tip temperatures and accelerated tool wear. Machining speeds have to be considerably reduced to
