Process Analysis for the First Two Steps of the SCM453H Bolt with a Modified Molding Process For a easier bolt molding, an extrusion process, the 2nd step of the molding process, was moved to step 4, and the bolt head section was exclusively molded in steps 2 and 3. As a result, the...
5.11). As in the conventional cycle, this is a two-step process. First, the preform is injection molded. After being clamped in the blowing mold, the hot preform is stretched axially and then expanded into the shape of the mold cavity by means of air pumped through the same rod. ...
(1) One MBP core is unfolded by increasing the force, immediately followed by relaxation to 5 pN to avoid unfolding other MBP cores. Some C-terminal helices also unfolded in this process. (2) After a waiting period, ClpB binds the unfolded part and translocates it completely. (3) ClpB ...
A process is proposed for producing extruded surface-active ingredients for use for food production, in which a carrier, before the start of extrusion, or in a process step during the extrusion, is hydrophilized by addition of hydrophilic emulsifiers and the surface active ingredients to be extr...
To manufacture the outer ring of a self-lubricating spherical plain bearing with titanium alloy, a two-step extrusion forming process was proposed. Taking a GE15DE1TK spherical plain bearing as an example, the finite element simulation model of the forming process was established, the forming ...
We built a simple model which predicts the probability of formation for all possible loops by quantitatively combining the contribution of each step in this process (Fig. 1f). First, the probability of CTCF binding at each genomic binding site is described by the chemical equilibrium: $$p_i ...
In the present study, the material flow during multi-hole extrusion process for producing a hollow and thin-walled profile was revealed by means of numerical simulation based on the Arbitrary Lagrangian Eulerian (ALE) method. The effects of eccentricity ratio, shape of the second-step welding ...
Process for die extrusion of melted polymers that reduces die lip buildup and its deleterious effects. Direct extrusion of mixed polymer pellets and filler concentrate pellets in one embodiment avoids a precompounding step and reduces th... RL Jacobs,BR Jones,SE Knothe,... 被引量: 20发表: 20...
In this process, a billet of aluminum is pushed by a RAM through a die land that is the desired product shape. The extrusion process is considered to be the most effective way to fabricate parts that need to have a uniform cross-sectional area. The high pressure and high temperatures ...
