Solve four common problems in PET stretch blow molding
The knowledge of blow molding technology provides tips on how to solve the uneven wall thickness in stretch blow molding. Although this is a vital issue, it is not the only issue that processors must deal with every day. Here are four other frequently asked questions, applicable to single-stage and two-stage processes.

The larger the build volume of the 3D printer, the greater the chance of building a whole object
When founder Scott Crump invented Fused Deposition Modeling (FDM), he was looking for "a simple way to make a toy frog for his daughter." In 1988, he applied for a patent for a hot glue gun under CNC control, which has since become one of the pillars of the 3D printing industry.

These variables in injection molding must be strictly controlled or rework costs are high
Re-grinding refers to materials that have been processed at least once, and then the gate, waste, etc. are ground or shredded. Please note that even the most "primitive resins" may have one or more processing histories, because they are compounded and pelletized during manufacturing.

The Preferred Structure Of Aircraft Aluminum Alloy 7A09
Among the aluminum materials for aerospace vehicles in China, 7A09 alloy is one of the preferred high-strength alloys for the main stressed structural parts. The semi-finished products available include plates, strips, bars, profiles, thick-walled tubes, forgings, etc. The chemical composition is more reasonable than that of 7A04 alloy, so it has superior comprehensive performance and becomes one of the designer's main materials. Its chemical composition (mass%): 0.5Si, 0.5Fe, (1.2—2.0) Cu, 0.15 Mn, (2.0-3.0) Mg, (0.16-0.30) Cr, (5.1-6.1) Zn, 0.10Ti, other impurities are individually 0.05, totaling 0.10, and the rest is Al.

7A04 Alloy - Yield Strength Close To Tensile Strength
7A04 alloy is an Al-Zn-Mg-Cu series heat-treatable aerospace super-hard aluminum alloy, which can be heat-treated and strengthened. Its composition has been listed in GB/T3190-2008, and it is compatible with the B95 alloy of the Soviet Union and Russia and the AlZnMgCu1 of Germany. .5.3.4365 alloy is equivalent, because in 1944 the Soviet Union’s 95th factory successfully trial-produced this alloy semi-finished product, hence the name B95 alloy. In 1957, China Northeast Light Alloy Co., Ltd. (then Harbin Aluminum Processing Plant) produced this alloy with the help of Soviet experts. Alloy plates and extruded materials.

Three Advantages Of The "High-Strength Arc" Cover Of The Electrolytic Cell
PTJ Hardware 420kA electrolytic aluminum large-scale pre-baked tank cover is a "flat type" cover used in the initial construction. After 5 years of operation, its weaknesses have gradually emerged, with low strength, severe deformation, and poor airtight insulation, resulting in poor operational safety and low energy conservation and environmental protection effects in production. For this reason, in 2018, the company replaced all 296 electrolytic cell cover plates step by step with "high-strength thermal insulation and energy-saving arc" cover plates.
