Kickstart: Is it working, or working out, at Peloton's new $400M factory?

Some of you may refer to work as being on a treadmill. Does that apply if you’re actually building treadmills?Peloton, the fitness company with “smart” exercise bikes and treadmills, says it will invest $400 million for a U.S. factory in Troy, Ohio, just south of Toledo. (Peloton refers to it as “POP”) will be a 200-acre, 1 million-square-foot plant with manufacturing, an office and amenities. It will create 2,174 jobs, the company announced May 24.The company did not specify if it will have any in-house molding, but its bikes and treadmills both use plastics extensively, so it will need to rely on local suppliers if it doesn’t make its own parts. Peloton also owns the Precor brand of exercise equipment.Having U.S. manufacturing will help the company respond more quickly to demand, without risking the type of delayed delivery issues that have popped up during the pandemic.”While we will continue to invest in our Asian manufacturing footprint as well as our existing facilities in the U.S. via our Precor sites, the new Peloton Output Park gives us a massive strategic lever to make sure we have capacity, quality and economies of scale … for years and years to come,” Peloton CEO and co-founder John Foley said in a news release. The International Atomic Energy Agency is making headlines for its work in plastics pollution.You read that right. The United Nations agency, which most often makes news for its work in the world’s nuclear weapons hot spots, has launched a program to see how radiation technologies can help reduce Plastic waste.In a , IAEA head Rafael Mariano Grossi said they can help in two ways: by employing isotopic tracer techniques to better track microplastics and developing technologies that use electron beams to break down plastics for recycling.IAEA said it technical research projects directly related to its plastics work. The next Rubbermaid-brand storage tote you buy may be a little greener, both literally and figuratively.Molder United Solutions announced May 25 that it has extended a licensing agreement with Rubbermaid Inc. to continue producing ActionPacker, Cleverstore, All-Access and Roughneck storage totes and added that the companies are also , made from 100 percent recycled resins and fully recyclable.The EcoSense proprietary storage containers “are made in a hunter green color to reinforce the opportunity for retailers and their customers to support a fully sustainable, closed-loop recycling initiative,” the companies said.United Solutions molds at sites in Leominster, Mass., and Sardis, Miss. Do you have an opinion about this story?

What is the component group of the linear motor drive device of the high-speed machining center

Nowadays, many high-speed machining centers use linear motors to drive linear three-axes. The way high-speed machining centers use servo motors + rolling screws to drive linear three-axes has gradually decreased. At present, most high-speed machining centers have adopted linear The motor drives the linear three-axis, and the linear motor directly drives the linear three-axis, which directly eliminates the part that converts the rotary motion into the linear. The following editor will introduce what components the linear motor drive device of the high-speed machining center consists of.
Linear motor drive unit composition
The linear motor drive device is composed of a rolling guide, a position measuring system, and a linear motor. At this stage, domestic high-speed machining centers that use linear motors to drive linear three-axis are relatively few, but now high-speed machining centers in advanced foreign countries have slowly begun to use linear motors to drive linear three-axis, such as the high-speed The machining center adopts linear motors, and its feed speed is 2-3 times faster than the speed of traditional servo motor + rolling screw. Traditional servo motor + rolling screw drive linear three-axis feed speed is the highest At 48m/min, the feed speed of the linear three-axis drive using a linear motor is up to 120m/min. It can be seen that the feed speed of the traditional servo motor + rolling screw drive linear three axis is not as fast as that of the linear motor drive linear three axis.
Features of Linear Motor Driven Linear Three-axis
The linear three-axis driven by the linear motor has the characteristics of fast speed, excellent rigidity and high efficiency. Nowadays, the use of linear motors to drive linear three-axis is still not the mainstream, because the linear three-axis technology of linear motors is still mature enough, and there are many problems in linear motor technology, such as high price, high heat generation, and poor transmission stability. However, it is foreseeable in the future that linear three-axis technology driven by linear motors will gradually mature and the price will gradually decrease. Therefore, in the future, linear three-axis technology driven by linear motors will slowly be adopted by various cnc machine tools, and servo motors + Rolling screws will gradually decrease in cnc machine tools. The cruel market and the survival of the fittest understand the truth, and those who should withdraw from the stage will inevitably withdraw.

Differences between DSC and PLC control systems

DSC and PLC control systems are very commonly used systems in the industrial control industry, so what are the differences between these two control systems? Which is better? PTJ will introduce to you.

In fact, the design principles of DCS and PLC are quite different. PLC was developed by mimicking the original relay control principle. In the 1970s, PLC only had switch logic control. The first application was the automobile manufacturing industry. It stores instructions for performing logical operations, sequence control, timing, counting, and operations; and through digital input and output operations, it controls various machinery or production processes. The control program compiled by the user expresses the technological requirements of the production process and is stored in the user program memory of the PLC in advance. When running, it is executed one by one according to the contents of the stored program to complete the operations required by the technological process.

There is a program counter in the CPU of the PLC that indicates the storage address of the program step. During the program running, the counter is automatically incremented by 1 every time the program is executed. The program is executed from the initial step (step number is zero) to the final step (usually END) Instruction), and then return to the initial step of cyclic operation. The time required for the PLC to complete a cycle operation is called a scan cycle. For different types of PLC, the cyclic scanning period is between 1 microsecond to tens of microseconds. The cyclic operation of the program counter is something that DCS does not have.

When users choose the DCS and PLC control system, they can choose according to their own situation and requirements, so that they can be handy when running in the future.

New Presses, Robots And Low-Pressure Process

At its annual Technology Days conference and exhibition in Lossburg, Germany, Arburg GmbH + Co. KG introduced its largest all-electric injection machine yet, available with optional hydraulic accumulator-assisted injection, as well as the company’s largest vertical hydraulic machine to date and a line of entry-level robots with enhanced programming functions. The April meeting also demonstrated Exjection, a new sliding-mold, low-pressure “intrusion” process that allows production of long parts not suitable for extrusion.

Arburg expanded its electric-driven Allrounder A series with a new 220-ton Allrounder 570 A model (570-mm tiebar spacing). It is available with the company’s largest size electric injection unit, capable of a 15.3-oz, 28.9-in.3 shot—or with Arburg’s largest accumulator-assisted hydraulic injection unit for higher speed (55 mm/sec) and shot sizes up to 29.1 g/55.1 in.3 The machine also has Arburg’s Selogica Direct touchscreen control.

Arburg expanded its Allrounder V line of vertical/vertical machines with a new 55-ton Allrounder 375 V model, the largest in this hydraulic line. It has a fixed lower mold platen and down-stroking C-clamp.

Meanwhile, Arburg rolled out entry-level, three-axis, top-mounted beam robots, called the Multilift V Select series. They are based on the Multilift V series with its cantilever design and ease of integration with Arburg’s press controls. But the new models have a predefined set of features so they can be offered at lower cost. Sizes are available for each machine in the Allrounder A and S series. They handle maximum loads of 13.2 to 33 lb.

They have pre-programmed sequences for removing and setting down molded parts, although user programming of other actions is possible. A new robot teach-in function on the Selogica Direct machine control eases programming. In this teach mode, the robot is moved manually in a step-by-step sequence, while the positions are recorded automatically by the controller. The Selogica Direct control generates the robotic sequence and integrates it into the machine cycle. Robot movements can then be fine-tuned through the controller.

A new low-pressure process that can mold long, thin-walled profiles integrating functional or decorative geometries was demonstrated by co-developers IB Steiner engineering consultants and Hybrid Composite Products GmbH, both of Spielberg, Austria. Their Exjection process provides a means of incorporating discrete features into a long profile, which is difficult or impossible to achieve by extrusion, while also accommodating low clamp tonnage.

In Exjection, a long mold slides either vertically or horizontally past a stationary injection gate. The process fills the mold continuously from the side rather than from the end, keeping flow length short, as the gate is always just behind the melt front. This method, sometimes called intrusion molding, reduces clamp requirements and stresses in the part. Proprietary controls coordinate mold travel with injection speed to ensure part quality.

Exjection allows a small press to mold parts up to 1000 mm long with a cross-section up to 10 x 16 mm and wall thickness from 1.5 to 1.8 mm. IB Steiner sells a license for 40,000 Euro ($61,500) per machine, which includes the control software. Both Arburg and Engel offer machinery for the process (see Learn More). At Arburg’s event, the Exjection process ran on the new Allrounder 375 V vertical hydraulic press, which was modified with an electric injection unit for precise screw-position control, electric-driven mold carriage and core pull, plus cavity-pressure sensors at the gate and end of fill.

Internal stress and warping

Internal stress and warping

When thick sections are moulded,rapid changes in temperature can cause thermally induced stresses due to differential expansion. If surface layers cool faster than the interior through poor conduction, the contraction of the surface will be greater than the interior thereby setting up stresses which can lead to warping and even failure in service at less than predicted stress levels. Thermal stresses induced during manufacture can be reduced by annealing during moulding or after moulding.

Internal stresses can also arise from flow induced anisotropy. Anisotropy arises from two principal sources: molecular orientation and the alignment of directional fillers such as fibres.

Molecular orientation results from melt flow where the polymer chains are forced to change from their random coil state (ideally) to an elongated coil. The degree of elongation depends primarily upon the nature of the polymer and the shear rate (stress) experienced in flow. Shear rate depends on channel dimensions and increases as the channel cross-section decreases. Typical shear rates in practice are 1000-5000 S in injection

Shear rate depends on channel dimensions and increases as the channel cross-section decreases. Typical shear rates in practice are 1000-5000 S in injection moulding. The degree of coil distortion can be quite marked. On emerging from the channel (e.g.gate), the elongated coil will attempt to revert to the relaxed random coil state and if it can do so,the product will be isotropic. In practice,this ability to revert is hindered by

  • loss of mobility in the polymer due to cooling;
  • continued flow into the mould cavity.

The result is frozen molecular orientation in the general direction of flow. The degree of orientation is low compared with that which is deliberately induced in fibre and film production,but it can nevertheless be significant.

Frozen orientation produces stress which weakens the product and causes failure at lower applied stress levels since cracks can propagate more easily in the flow direction. However,stiffness is increased in the flow direction. Frozen orientation can also lead to dimensional instability. The application of heat induces molecular relaxation which produces warping or even gross distortion.

Molecular anisotropy can be minimised by using generous flow channels, low shear rates and slow cooling. Thin sections should be avoided. Fibres (usually glass) of length 0.3-0.5 mm incorporated into thermoplastics as reinforcements increase the anisotropic effects described above because the fibres tend to orientate in the same flow direction as the polymer chains. Mineral powders of aspect ratio greater than unity (e.g. talc) also contribute to anisotropy but less so than fibres.
