How Long Has Makray Manufacturing Been in Business?

Makray manufacturing has been in business for over 60 years, with the vast majority of that time spent at our current location.  Don’t worry; we’ve got all of the high-tech equipment you’ll need to get your project done!

How Large is Your Facility?

Our building is pretty darn big.  With 100,000 square feet at our facility, we’ve got the machines and the room for most any project.  Check us out on google maps, you’ll see.

What type of machines and capacities do you have?

We have a wide range of injection molding presses available to suit your needs.  Clamping force ranges from 170 ton all the way up to 1100 ton.  Our newer Husky machines are so effective though, it’s not uncommon for us to run jobs that our competitors needed 1500+ ton machines for in our 800-1100 ton Husky presses.  Why does that matter?  Cause it will save you money.

I have a mold, when can my project start running at your facility?

As a custom molder, we carefully balance incoming new jobs with current customer’s production runs.  We have enough machine time and flexibility in our scheduling that we can usually start injecting plastic into your mold within 1-3 weeks after receiving your mold.

We don’t have a mold yet, but we have drawings, should we contact you!?

If you have any questions before the injection molding process, we can help.  If you have engineering drawings for your mold, we can assist you in the mold making process.  Though we are not a mold maker, we have extensive engineering knowledge in-house, and we work very closely with our mold making partners to ensure that not only will you receive a suitable mold, but one that will run well once it arrives at our facility.

We don’t have a mold OR drawings yet, what now?

If you are a company that is familiar with the injection molding process and are working on a new product then we may be able to assist you.  Some companies we work with consult us on some of their ideas of how they would like to create a final product, whether it should snap together or require other assembly, etc.  We would make our best recommendations on design so that you can go back to your engineering department and begin drawing out a product that will be highly compatible with the injection molding and assembly process- helping to save not just production headaches, but end user ones too. 

If you are an inventor we highly recommend you contact local engineering agencies first.  It is important that your product is not only a good idea, but designed to be compatible with the plastic injection molding process.

I am an inventor, should I contact you regarding my idea?

Although we love innovation borne in the good old U.S. of A., we highly recommend that inventors seek out professional design and engineering firms to help bring their products up to spec, run feasibility tests, etc.  We typically don’t charge for our consulting because most of our customers we already do work for or have engineering drawings that are compatible with the injection molding process.  With the invention process though, we cannot recoup the cost of prototyping or consulting.  If you can concept the part yourself though, you should consider doing a Kickstarter campaign to help get you through the engineering phase.  Good luck!  We’ll be here when you need high volume.

Are you an ISO 9001:2008 certified company?

Nope.  But a lot of our clients are.  How do we do this?  As a custom molder we work with many different customers, some who require very little quality control; is it the same size, does the color look about right, does it function.  Other customers are much more rigid, requiring first article inspections, constant quality standards, tolerances, etc.  With our ISO customers we operate under a green card.  They come in and audit us, we prove that we can mold the part to spec, and then we run it.  You can too.  We go through this process a handful of times per year with new clients, so it’s nothing new to us.  The best thing you can do is contact us.

Can you handle complex assemblies and finishing processes?

We have a large section of our building dedicated as a finishing department.  For assemblies too complex to be done at the press, this is where things would be handled.  We do anything from highly complex assemblies to sonic welding, painting, decorating, packing, labelling, electrical assembly, potting, riveting, and more.  If you have a more specific question about or capabilities, contact us.

How many shifts does Makray Manufacturing operate?

When we’re busy we operate 7 days a week, 24 hours a day, or 3 shifts.  Typically we operate 5 days a week with 3 shifts.  We have a very stable and experienced workforce of 100, and work closely with a staffing agency for any additional labor needs.

Do you have any other locations other than 4400 N Harlem in Norridge IL?

Nope.  We’ve been here a long time, and we only have one location in the United States.  At 100,000 square feet, it’s plenty of room for us.  We have no outsourced manufacturing locations abroad either.  We’re proud to be an American manufacturer.

How long will it take to get my parts made by you?

Typically we are producing good parts within 1-3 weeks after receiving your mold.  Sometimes it takes longer, as there may be issues with a new or existing tools, sometimes it works right out of the gate.  On the lower end we see many single cavity tools push out 2000-3500 parts per day, if your tool can run faster, or you have a multi cavity tool, the amount of parts that can be produced goes way up.

Makray Manufacturing was one of the first molders in the Chicagoland area, opening in 1948 and has been at its current location at Harlem and Montrose for over 60 years.  Early on as a molder we found success in producing the iconic “Tile Master Tiles” which were found throughout the Midwest in the 1960’s.  Times changed and so has Makray.  Not many molders can boast the success and perseverance that we have had.  Through the booms and the busts Makray has stood tall as a molding icon in Chicago, consistently performing by adapting to market changes and delivering high quality products and services to our customers.

Located in the heart of Chicagoland we are situated perfectly in between O’hare Airport and Downtown Chicago operating as a custom plastic injection molder.  We don’t run any in house products.  Rather, we are the go-to source for plastic injection molding projects from design to prototyping and tool building all the way to final plastic injection molded parts for our customers across many industries.

We specialize in working with a broad range of customers in many different industries including; point-of-purchase, telecommunications, automotive, marketing products, industrial products, office supplies, medical accessories, and consumer products.

Our customers choose us not only because we have the tools to get the job done, such as molding machines from 170-1500 tons, but because our core staff of dedicated molding experts has experience in molding operations, finishing, design, assembly, and shipping.  We’ve handled everything from the simplest parts to the most complex assemblies out there, and pride ourselves on our ability to quickly ramp up our customer’s projects where others have failed.

Over the last few years we have also made incredible progress by continuing to improve our operations by utilizing high efficiency molding machines decked out with upgrades like gas-assist, having on-press robotics, utilizing efficient on press work cells, as well as implementing new software to help manage plant operations in the 21’st century.
