超越商品钣金穿孔-芝加哥穿孔器如何扩展到精密钣金制造精确穿孔不再仅仅是穿孔。亚博ag捕鱼它提供了整个穿孔和装配板金属组件。这家拥有200名员工的芝加哥制造商为在一个整合的行业脱颖而出做了很多工作。
射孔行业曾经由聚集在芝加哥和宾夕法尼亚的众多小公司组成。这些商店最初是为了满足农业设备和(特别是在宾夕法尼亚)采矿部门的需要而成立的。但几十年来，这个行业发生了变化。穿孔过程本身已经被视为一种商品服务，这反过来导致了巩固。今天，只有少数几家大型公司仍然存在，其中一家是精确射孔(AP)，总部位于芝加哥，拥有200名员工。亚博ag捕鱼但大约十年前，美联社开始走上一条新的道路。经理们不希望公司只生产穿孔的纸。他们想要制造并组装这张纸，把它做成更大更复杂的东西。如今，这家公司不再只是打洞;这是关于制造原始设备制造商可以很容易地放入其最终组装件的组件，而承包商可以快速安装到建筑物上。这与该公司70年前的情况大不相同，当时一个名叫拉尔夫·科恩(Ralph Cohen)的废品小贩爱上了打孔——不是为了打孔过程中产生的填洞纸，而是为了这些纸留下的东西。在1942年创办美联社之前，科恩对蛞蝓的热爱并没有成为一名穿孔者的意图。他陶醉在交易中——低价买进废料，高价卖出——他最大的废料来源恰好是芝加哥周围的穿孔屋。“He was always a peddler at heart, and he became fascinated with his perforating clients because of the amount of scrap that they generated,” said Aaron Kamins, Cohen’s grandson (on his mother’s side), who took over as president 10 years ago. “He fell in love with the byproduct—the slugs that he would get from the perforators, and he said, ‘You know, I could develop those slugs myself.’ So he put in his first machine to generate those slugs.”During the early years the perforation work complemented Cohen’s primary scrap business, but over the years this gradually shifted more toward perforation. AP moved into its current facility in 1952 and remained a small enterprise for decades. Then in 1982 managers jumped on an opportunity to purchase Standard Perforating, a competitor just a few miles away that had just undergone a labor dispute with its union and was struggling financially. AP moved Standard Perforating’s employees and machines over to its own facility. “That basically doubled the size of the business overnight,” Kamins said, adding that in 2002 AP purchased another Chicago-based perf house, Semrow Perforated Products.

Between 2000 and 2005, Mike Beck, director of architectural and engineered sales, and new product development, helped bring in machines to expand AP’s capabilities. “Our existing customer base’s demand for fabrication was really growing,” he said.Then in early 2005 came a phone call that accelerated the company’s push into fabrication. It was a contractor for the new American Airlines World Gateway terminal at JFK, and he had a problem. The new concourse had thousands of perforated ceiling panels. The perforations weren’t terribly unusual—0.125-inch-diameter holes punched in 0.050-in.-thick aluminum; the holes’ staggered orientation (lining up horizontally but not vertically) aided noise reduction and airflow.Fit-up between the panels was critical, and this was what the contractor called about. Thousands of panels had arrived at the site, perforated and with edges flanged, but when they were installed, some bowed slightly. Many panels had dimensions that weren’t exactly what they should have been, and this wreaked havoc on fit-up. On top of all this, many panels arrived at the site severely damaged.The contractor sprung the question: Could AP provide dimensionally accurate perforated panels? One more thing—the grand opening is just 90 days away.AP dove into the job, manufacturing 17,000 panels with acoustic backing material and the proper perf patterns that ensured noise reduction and proper airflow. It worked with a corrugated box manufacturer on packaging so the panels would arrive at JFK without a scratch.Most significant, at least when it comes to the company’s evolution, was AP’s work with Advanced Display, a precision sheet metal fabricator in Chicago. At the time, the fabricator focused on the point of purchase (POP) display industry (hence the fabricator’s name), but contracted with different companies as well, including AP.Advanced Display had the precision press brakes and forming expertise this job required, plus the capacity to manufacture the panels within the short lead-time required. The 2- by 5-foot perforated panels required a tight dimensional tolerance in length, width, and edge-flange depth.Working together, AP and Advanced Display churned out 170,000 square feet of perforated panels, fabricating and painting them on time to be painted and installed before the grand opening in July 2005, when then New York City Mayor Michael Bloomberg spoke below the space-age, dramatically white ceiling of the new Terminal 9.

The leveling also makes the punched blanks consistently flat for downstream forming and assembly, especially for the component work that flows through Accurate Metal Fabricating.

And we have just five turret presses.” (Go tohttp：//www.thefabricator.com/article/punching/oging-beyond-commodity-she ...要查看更多的“数量考虑”）与Holesmany OEM和Pop客户的品牌已经接近了AP关于将其品牌标志设计成穿孔板的方式。AP employed programmers experienced in hole-intensive jobs on the turret punch press, and programming logo shapes, while intricate, wasn’t a major challenge for them.As Kamins recalled, “After we did this, several clients came to us with a picture and asked, ‘Can you punch this?’”Kamins added that the request evolved into a service AP now calls Picture-Perf, in which the company punches holes in a pattern that creates a logo, graphic, or picture.“We saw similar things done in different ways before,” said Beck. “So we asked, ‘What if we use different-sized holes with different open areas and spaces between those holes?’”The pattern can be small, in the corner of one panel on a POP display, or cover a building facade. For the new apartment complex in downtown Chicago, AP is providing 51 panels, each 5 by 13 ft., that when assembled depict a giant picture of the Greek Parthenon.
