The Industrial Technology Research Institute (ITRI) has developed an artificial intelligence-assisted monitoring system that reduces plastic waste created in the process of injection molding manufacturing.
The system has been adopted by several local factories, and increased yields and curbed product defects by 3 percent and 30 percent respectively, the institute said on Tuesday.
Although plastic reuse techniques are widely used, there is some plastic waste that cannot be recycled, ITRI Smart Sensing and System Technology Center director Chu Chun-hsun (朱俊勳) said.
The parameters of injection molding equipment influence its yield rate and the production of plastic waste, Chu said.
The yield rate depends on the experience of the operator, he said, adding that considerable time and effort is required to produce an adequately high rate.
The monitoring system conducts real-time monitoring of changes in pressure and temperature throughout a manufacturing process in which plastic is melted at high temperatures and molded into new forms, Chu said.
The system facilitates multiple digital online tasks, such as production history management, in-process energy consumption monitoring and virtual quality testing, he added.
Equipment producers can upgrade individual machines by using the program to boost product value, while system users can establish injection molding production lines that improve product quality and minimize plastic waste, Chu said.
The system has been adopted by Victor Taichung Machinery Works Co in its injection molding machines, and was well received in factories in central and southern Taiwan, he said.
Chinese spouse and influencer Guan Guan’s (關關) residency permit has been revoked for repeatedly posting pro-China videos that threaten national security, the National Immigration Agency confirmed today. Guan Guan has said many controversial statements in her videos posted to Douyin (抖音), including “the red flag will soon be painted all over Taiwan” and “Taiwan is an inseparable part of China,” and expressing hope for expedited reunification. The agency last year received multiple reports alleging that Guan Guan had advocated for armed reunification. After verifying the reports, the agency last month issued a notice requiring her to appear and explain her actions. Guan
A preclearance service to facilitate entry for people traveling to select airports in Japan would be available from Thursday next week to Feb. 25 at Taiwan Taoyuan International Airport, Taoyuan International Airport Corp (TIAC) said on Tuesday. The service was first made available to Taiwanese travelers throughout the winter vacation of 2024 and during the Lunar New Year holiday. In addition to flights to the Japanese cities of Hakodate, Asahikawa, Akita, Sendai, Niigata, Okayama, Takamatsu, Kumamoto and Kagoshima, the service would be available to travelers to Kobe and Oita. The service can be accessed by passengers of 15 flight routes operated by
GIVE AND TAKE: Blood demand continues to rise each year, while fewer young donors are available due to the nation’s falling birthrate, a doctor said Blood donors can redeem points earned from donations to obtain limited edition Formosan black bear travel mugs, the Kaohsiung Blood Center said yesterday, as it announced a goal of stocking 20,000 units of blood prior to the Lunar New Year. The last month of the lunar year is National Blood Donation Month, when local centers seek to stockpile blood for use during the Lunar New Year holiday. The blood demand in southern Taiwan — including Tainan and Kaohsiung, as well as Chiayi, Pingtung, Penghu and Taitung counties — is about 2,000 units per day, the center said. The donation campaign aims to boost
The Central Weather Administration (CWA) said a magnitude 4.9 earthquake that struck off the coast of eastern Taiwan yesterday was an independent event and part of a stress-adjustment process. The earthquake occurred at 4:47pm, with its epicenter at sea about 45.4km south of Yilan County Hall at a depth of 5.9km, the CWA said. The quake's intensity, which gauges the actual effects of a temblor, was highest in several townships in Yilan and neighboring Hualien County, where it measured 4 on Taiwan's seven-tier intensity scale, the CWA said. Lin Po-yu (林柏佑), a division chief at the CWA's Seismological Center, told a news conference
