Molding cycle time. The following formula expresses the total cycle time t for injection-molding. Formula 19 t = td + ti + tc Whereas: td: intermediate time The sum of the time required to open and close the mold (referred to as the dry cycle in injection-molding), to remove the molded product from the mold, to place inserts in the mold and to apply parting agent. ti: injection time. polycarbonate with cold density or sp gr of gr/cc. Molding cycle time is seconds and shot weight is grams. Hot runner supplier tells us the melt channel’s volume is 88 cm 3. We convert the 88 cm 3 to styrene grams as shown: We convert the oz to grams as shown:File Size: KB. The wall thickness of a part will directly affect the cycle time; thicker walls create longer cycle times while thinner walls create shorter cycles that’s why thin wall molding has cycle times in the 2 to 5 seconds range.

Recording: CDRWIN v.3.9f

An updated version of the GoldenHawk CDRWIN utility has been released, which allows you to burn CD-discs of the following formats: AUDIO CD, CDROM (Mode1), CDROM-XA (Mode2), CD-I, Mixed-Mode CD, Multisession CD, Karaoke CD + G and CD-Text. Supports ISO and Joliet standards, TAO and DAO modes, work with disc images, Overburn function, BURN-Proof technology and the ability to create bootable discs. The program has a built-in scripting language CUE SHEET, a utility for preparing a disk image and an MP3 decoder.

CDRWIN can work with most burners on the market and some models of CD duplicators. Also, the program implements the ability to simultaneously work with several writing drives (up to 32 MMC-compatible drives).

There are no details about this release yet.
