American Iron & Alloys
Yes! We can provide value added processing like; tubing to size, milling squares and rectangles, plate cutting and high volume production cutting.
We have the availability of bronze with our specialization on bronze bushing and flanges.
We offer a wide range of sizes for our gray and ductile iron, including 1.5” to 24” diameter and we have equally a wide range of square and rectangle sizes.
Molding is more competitive every day. Time is money. Our purge compounds are designed to quickly and efficiently remove previous resins, colors, and contamination that slow the changeover process. A quality purge will significantly eliminate scrap parts from contamination and reduce changeover times.
No. Most of our purge compounds are ready-to-use. No mixing or measuring required.
It can vary based on the resin, processing temperature, etc. We typically recommend a hybrid of chemical and mechanical. We find other products on the market offer aggressive mechanical purge compounds and/or cheap regrind resins such as cast acrylic will damage screws, barrels, tips and other components over time.
We suggest using purge anytime you change resins, colors, tools or shut-down. Regular use of purge will minimize color staining and carbon build-up.
Our purge compounds are safe for use with hot runners, screws, barrels, hot tip and valve gated hot runners systems.
In most cases we identify 1-2 purge formulations ideal for resins currently processing. This can vary depending on resin and processing temperatures.
Yes. Virtually all our formulations are safe for hot runner systems. Your local SEDLOCK Companies sales representative can help identify the ideal product for your specific application.
Yes. A SEDLOCK Companies sales representative is available to help identify the ideal formulation for your applications. We can come to your facility for an on-site purge trial as well.
Yes. Our products are low odor, low smoke with no harmful fumes. Other non-typical alternatives such as laundry detergent and pumice soaps an emit dangerous fumes.
Yes. Our purge can be recycled as regrind and added back to molded parts. It can also be sold back to scrap dealers.
Yes. We highly recommend using it for both. Our products are thermally stable for shut-down and start up allowing extended time for purge to remove color and contamination. Keeping the injection unit full of purge will minimize feed screw contact with the barrel ID while eliminating the introduction of oxygen that can promote carbon build-up.
Yes. We do recommended specific metals and coatings ideal for resins processing. Ask your local SEDLOCK sales representative for more details.
Yes, but without any chemical or mechanical cleaning power changeovers are typically slow and tie up valuable press time.
Purge is available in a wide range of costs. Most range from $3 to $8 per pound. We encourage molders to evaluate purge on a 'cost per purge' basis over cost per pound. All ChemTrend - ULTRA PURGE compounds are low consumption requiring less pounds for an effective purge. Some purge compounds are inexpensive, but require 2-3 times more pounds for an effective clean which equate to a higher cost per purge.
Concor Tool & Machine
Concor utilizes Solidworks 3D CAD for our engineering work. Our facility includes new CNC machines along with traditional manual machining centers such as lathes, grinders, mills, hones, saws, welding machines, and polishers. We have built and modified many custom machines over the years to perform our specialized work. Concor continues to invest in modern technology and over the last four years has added a new centerless grinder, new VF5 CNC machining center, new lathe, and a new Plasma Transfer Arc welding center to our facility.
Concor Tool & Machine manufactures, screws, barrels, tips, end-caps, tie-bars, complex mixing sections, along with other parts for the plasticating units of injection and extrusion molding machines. We also rebuild worn screws and reline barrels at our factory. Details on these products and services may be found on this site. Our factory operates two shifts; Concor engineers also work at the factory location.
Yes! This is what we do. We are experienced in challenging wear, mixing, and high-precision applications. From highly complex mixing sections, to simple and strong components, we know our work well. Upsizing, downsizing; we do it all. Our engineers utilize 3D CAD and we have built a massive print library. Over our many years we have developed valuable experience in a wide range of processes, and we are happy to put this experience to work for you.
For 35 years. We have a deep understanding of the design, manufacturing, and rebuilding of these components, and we make screws, barrels, and tips for all makes of molding machines.
Embassy Powdered Metals
The general rule is if the part is smaller than your hand and weighs about 3 lbs, we can produce it.
There is no difference at all. It is the same component, just different terminology.
Our materials do align themselves with wrought materials but do have some limitations to them when it comes to ductility and certain ways loads are applied. Powder metal is made in a vertical pressing action so the strength in compression is matching but if there is any twisting action it is a little less comparable. It is best for Embassy Engineers to review the application on a case by case to ensure it is a proper fit.
The vertical length is limited by our presses and the ability to achieve uniform density, with this said was need to be less than 3”.
Powder Metal can have assembly operations done to it after it is sintered, Embassy needs to understand this up front so we ensure the processing allows this for the customer.
Embassy does not use any Aluminum powders at this time, Embassy manufacture components using all the iron base materials, coppers, brass and both 300 and 400 series stainless steel.
Mainly any iron base but we have the ability to design in weight saving features up front.
Kuhn Special Steel
Because the integrity of centrifugal castings is so high, mechanical properties are very repeatable and consistent. When considering standard austenitic stainless steels (300 series), martensitic stainless steels (400 series) and duplex stainless steels, mechanical properties generally meet and exceed forging specification minimums. In certain other alloy cases, strength and/or ductility may be lower than forged materials. Please ask about your specific alloy requirement and a Kuhn metallurgical professional will be happy to give you an honest appraisal.
Very often centrifugal offer a very cost effective alternative to forgings. In most cases, pricing will be lower than a comparable forging in the rough machined condition. If finish machining is considered, the cost savings can be even greater. These savings can be realized with the added benefit of usually much shorter lead times.
In most cases, Kuhn Special Steel centrifugal castings are not subject to the current tariffs on steel coming from the EU. Our components are usually rough or finish machined and can only be used for the manufacturing process or machines for which they are destined. There are, however, certain circumstances where the tariffs may be applicable. Again, Kuhn Sales personnel will discuss your individual situation at the time of quotation.
Kuhn pours over 200 different alloys. Virtually all grades of austenitic (300 series), martensitic (400 series), Duplex (2205, etc.) and Precipitation Hardened (17-4PH & 15-5PH) stainless steels are poured. Other Super Austenitic (6 Moly, etc.) and Super Duplex (2507, etc.) are poured. Many air-melted (non-vacuum) Nickel base alloys are also poured such as INCO 600 & 625, Hastelloy C, C-276 along with many others. And finally numerous Cobalt alloys are poured as well.
