Blow Molding: New Machines Take on Challenging Shapes ...2016-12-28 · An external add-on hydraulic power unit is used to drive forming parts within the blow mold so that the shape of the cavity changes during blowing, reportedly allowing production of shapes that were formerly “impossible.” The same mechanism can also add inserted PP or HDPE handles that are mechanically locked into the the bottle during blowing.

Blow Molding - ScienceDirect2017-1-1 · Blow molding is the forming of a hollow object by inflating or blowing a thermoplastic molten tube called a “parison” in the shape of a mold cavity. The process consists of extruding or “dropping” a parison on which female mold halves are closed. The female mold halves contain the shape of the product to be produced.

Recycling of High-Density Polyethylene (HDPE or PEHD)2012-7-25 · The report stated that compared with 2015, HDPE bottle collection fell by 31.7 million pounds to 1112.1 million pounds, with the HDPE bottle recycling collection rate decreasing to 33.3% from 34.4%. ESE World B.V. carried out a test to demonstrate that HDPE can be recycled at least 10 times.

Blow molding troubleshooting guide - Plastics World2019-9-12 · Blow-up ratio too high. PROBLEM: Blow-out – Blow-out of parison • Increase land width of pinch-off. • Increase cooling, preferably in pinch-off area. • Use clamp pause on mold lock-up. • Slow mold closing speed. • Gradually reduce blow pressure to decrease inflation rate. • Increase clamp pressure. • Lengthen parison.

China 2+2 HDPE Bottle Blow Molding Machine Factory ...The 2+2 HDPE Bottle Blow Molding Machine, which equipped with a 2-parison die head, 2 shuttling mold clamps and 2-cavity blow moulds can make PE bottles with a volume less than 2 liters. For example, a square HDPE bottle with 500mL volume are produced at a rate of 350BPH and the 1500mL square bottle at production rate of 300BPH.

Oxygen Transmission Rate - an overview | ScienceDirect …They are superior to HDPE bottles in terms of their mechanical and optical properties, their lower flavor sorption (scalping) potential and substantially lower gas permeability values, e.g. oxygen transmission rate (OTR) at 4 °C/50% RH of a commercial 600 mL PET bottle is 19 μL day −1 compared to 390–460 μL day −1 for a commercial 600 ...

A Guide to Polyolefin Blow Molding - LyondellBasell2015-8-27 · die. Under moderate rates of shear, HDPE is moderately viscous. When it is forced at high speed through a narrow die gap, the HDPE melt is sheared at a fast rate; at this point it appears to have a low viscosity. Then, when it hangs from the die as a blow molding parison, under practically no shear, the same HDPE appears to be very viscous.

Common problems of HDPE bottle blow molding-Xinfuda2021-6-2 · 2. There are wrinkles in the bottom of the bottle. If the bottom temperature is too high, the pre-blowing is too late, the pre-blowing pressure is too low or the flow rate is too small. 3. The bottom of the bottle is thick and thin at the top. This phenomenon is mostly caused by uneven baking or insufficient temperature at the bottom of the bottle.
