The required screw diameter can be ascertained on the basis of the shot volume. The formula for the average residence time can be used to estimate the degree of utilization and the thermal load on the material.

All about Plasticizing Screws

Infrared heating technology has become established as the standard in the processing of thermoplastic composite materials. The focus is on process control. On the one hand, it is important that the heating process is fast, on the other hand, the material must not be overheated. It is also important to achieve excellent temperature homogeneity. Simultaneous processing of blanks with different thicknesses is a particular challenge.

ENGEL, headquartered in Schwertberg, Austria, is one of the globally leading companies in plastics processing machines. From individual injection moulding machines to integrated and automated production cells, ENGEL offers customised solutions for thermoplastic, thermoset and elastomer processing from a single source. ENGEL injection moulding solutions are used, for example, to manufacture automotive components, housings and other parts for electrical and electronic products, household goods, toys and leisure articles, packaging, and products for medical technology and health care. ENGEL‘s leading market position is founded on two cornerstones: on the one hand, high-technology business that initiates permanent further development and on the other hand, large-scale production to make our cost-intensive development work financially affordable. With nine production plants in Europe, North America and Asia, as well as subsidiaries and representatives in more than 85 countries, ENGEL has a global presence. From its foundation in 1945 to the present day, ENGEL has always been 100 percent family-owned.

An Eye on the Process –  a Handle on Quality

The area of application of cube molds has expanded to take in the production of technical parts. The new Allrounder Cube 1800 from Arburg with a clamping force of 1800 kN is providing the response to this trend. With its compact cube, this machine completes the portfolio of products at the lower end of the range.

Plastics Machinery Shipments Grew in Third Quarter

Shipments of primary plastics machinery in North America increased in the third quarter according to the statistics compiled and reported by the Plastics Industry Association’s Committee on Equipment Statistics (CES).

The Plastics Industry Association (PLASTICS), Washington, USA, announced that shipments of primary plastics machinery (injection molding and extrusion) in North America increased in the third quarter according to the statistics compiled and reported by the Association’s Committee on Equipment Statistics (CES).

The preliminary estimate of shipment value from reporting companies totaled USD 333.8 million in the third quarter. It increased 4.0% from the previous quarter and 8.8% from a year earlier. The value of shipments of twin-screw extruders rose significantly by 44.4% in the third quarter and was 61.2% above the third quarter last year. In the third quarter, shipments of single-screw extruders rose by 7.2% from the previous quarter and 15.9% from the third quarter last year. Injection molding shipments edged up 1.6% from the second quarter and 5.7% from a year earlier.

“Plastics equipment shipments picked up in the third quarter as the economy continue to emerge from the pandemic. Moreover, the increase in shipments was consistent with higher plastics production, which in the third quarter rose 4.2% or 5.9% from a year earlier. The upward-sloping demand for plastics equipment has not changed,” according to Perc Pineda, Ph.D. the Chief Economist of PLASTICS.

Survey on Market Conditions and Expectations for the Future

The CES also conducts a quarterly survey of plastics machinery suppliers that asks about present market conditions and expectations for the future.

In the third quarter survey, 75.5% of respondents expect market conditions to either improve or hold steady in the coming quarter – lower than the 92.7% of respondents who expressed the same view in the second quarter’s survey. As for the next 12 months, 75.0% expect market conditions to be steady-to-better. This is lower than the 78.7% of respondents in the previous quarter’s survey who were expecting growth in the next 12 months.

“While the survey results show that growth expectations have moderated it also reveals that plastics machinery suppliers remain optimistic about market conditions four quarters ahead,” said Pineda. 

Plastics machinery exports increased by 6.1% to USD 390.2 million from the second quarter. Mexico and Canada remained the top export markets of plastics machinery from the U.S. The combined exports to USMCA partners in the third quarter totaled USD 172.6 million, which was 44.2% of total plastics machinery exports. Imports fell by 3.0% to USD 848.4 million resulting in a USD 458.3 million trade deficit. The U.S. plastics machinery trade deficit decreased by 9.6% in the third quarter. U.S. trade data in the third quarter are in sync with the improving global trade outlook. The World Trade Organization now expects a 10.8% increase in global merchandise trade this year—an upward revision from its 8.4% projection in March.

“Data we’re seeing at PLASTICS confirm our prior projections that the outlook for plastics machinery in the second half of 2021 is positive albeit shipments will continue to fluctuate. The likelihood that supply-chain issues will continue to be a headwind in 2022 remains high. The globe is still emerging from the pandemic,” said Pineda.
