Dura STAT vs. Dura CRIB

The two most popular products of our cribbing and blocking line are Redco “Dura Stat” and “Dura Crib”. Customers often request quotations on both, or confuse each product, but the differences are distinct and important enough to create a write up. The “Stat” is Dura stands for “static” it is designed solely for cribbed storage of equipment that is not dynamic, IE. no movement. An example of a Dura Stat application would be lowering an engine onto the cribbing for storage. The Dura Stat set up should not be moved after the load is placed.

It is very important for Dura Stat that what is being cribbed is loaded vertically. The product is not resilient to sheer pressure and could break. Also, as a non-interlocking product, there could be slipping issues as well. Dura Crib on the other hand, is meant to be stacked and is commonly available in interlocking forms it is designed to handle applications where there may be a little dynamic movement. An example of this application would have Dura Crib providing cribbing for a railway maintenance vehicle’s outrigger feet. The stack of cribbing will endure vibration and oscillation as the load shifts on the feet while the vehicle works.

Simplicity = Savings

Customers with a budget in mind often ask us how they can reduce the price of their part. They think that the price is always tied up in expensive material costs but in reality it’s usually the labor costs or a complex mold that results in a high price. What you should understand is that the more complicated a part is, the more expensive it will be. In the case of a molded or extruded part, the tooling needs to be more complex and this takes more time and effort, therefore the mold will cost substantially more. In the case of machined parts this is even more acute as every hole, angle, and cut adds cost.

Labor for machining is quoted based off “passes” that is how many times a tool needs to touch the plastic material in order to make the cuts needed to manufacture the parts. These passes are the labor cost – the more passes, the more cost. A good example to discuss are “webbed” sheaves. These are sheaves or pulleys that have the sides machined out around the outside of the hub on either side. This has the sometimes beneficial property of reducing sheave weight because it’s now made of substantially less material. However, these weight savings mean lots of extra machining has to be done and this increases the cost of the sheave. Where lowest price is desired and weight savings are not critical, webbing is not advantageous to your application.

One service we offer to customers is that we provide “blanks” these are partially machined plastic parts that are not completed, just the general profile is done. Once the parts arrive on site the end-user themself then finishes the machining. An example of this is our Redco chain channel for sawmill applications. We can offer the channel pre-drilled with weld washers but this adds about $0.85/hole. Many customers elect to simply buy the channel and drill their own holes on site. Perhaps the best method to figure out if a part can be simplified is to just talk to one of our plastic experts. We’ll take a close look at the application and ask you if the part can be redesigned to a simpler format to save money.

Redco 90A Polyurethane Forklift Socks

Redco Forklift socks are an upgrade over traditional low-grade cold bonded rubber socks. A “forklift sock” is an elastomer solution that provides a covering to forklift forks, this makes them less likely to damage sensitive equipment being lifted. The problem is that the rubber sock covers easily delaminate from the forks and can also crack. This creates a situation where the loose sock causes an unsafe lift.

Unlike the cold bonded rubber, our solution uses a proprietary 90A polyurethane in a “hot bond” to the metal socks. This is a superior way of applying a sock solution and will vastly outwear rubber socks. In addition, our material is colored “safety yellow” for high visibility. The product reduces the risk of driver error and material damage while greatly improving grip when lifting. Redwood Plastics and Rubber can provide this service in two ways. Firstly, you can ship your existing steel forklift socks to our Langley, BC, Canada facility and we can re-coat the socks in-house. Alternatively, we can machine the complete new steel socks, coat them, and send them to your facility.

To Grease Or Not To Grease?

Whether or not to grease a plastic bushing is a frequently asked question, or even just an assumption customers make (that they need to). While there are times where greasing is important, and times where it is absolutely critical, in most cases with many materials you will not need to.  Avoiding the need to grease a bushing is a strong advantage plastics have over metal in application. Many plastics are self-lubricating and can come impregnated with solid or liquid lubricants. Certain bushings, such as the Rulons, will never require grease. In general, if you want to switch from a greases metal bushing and are flexible on material, an oil-filled option would be quoted. The cost difference between oil-filled and unfilled materials is about 30% so you need to judge how important it is not to grease.

In the case where an unfilled bearing grade material is required, grease grooves can be machined into the part. These would come with a “grease nipple” or small hole in the bushing to permit application of the grease. This is common for applications such as kiln wheel bushings or sprockets. That said, there is one case where you *must* grease and that is if the demands of your application exceed the P/V/PV ratio of the plastic. P/V/PV needs to be under all three maximum limits for the bearing material; however, that’s a discussion that requires it’s own article.

If you are looking for grease-less bearings or have questions on our Redco bearing materials please contact us.

24″ Diameter Tivar 88 Pipe Lining

The pictures below are of an application completed at our Langley, BC facility. This involved lining a steel pipe with an internal diameter of 24″ inches and is a job we’ve done several times before. It’s innovative work and we wanted to share some details and pictures in case the application might be of interest to other companies. The customer ships their pipe segments to our facility where the lining is done on site. We have fabricated 3/4″ thick Tivar 88 sheet that comes pre-scored to permit bending. This is important since Tivar 88 is not available in pipe format, so the solution must be made from sheet stock.

As you can see in the second picture there are not too many fixation points. There is a middle strip of plastic serves as a wedge, and the pressure alone holds the lining solution in place (though the strips on either side of the wedge also have fixation hardware, to help secure the wedge). Tivar 88 is a premium grade of UHMW polyethylene and its blue color is readily identifiable. It provides additional strength and slickness that virgin or reprocessed grades of UHMW do not. Tivar 88’s primary benefit is increased material flow and less material hangups. Secondarily, Tivar 88 provides a wear surface that protects the steel from wearing out.

Tivar 88’s lifespan will vary in applications but it is sacrificial, meaning that it will need to be replaced at some point. The performance benefits and increased life of the pipe do make up for the cost of the lining. While not important in this application, Tivar 88 does include UV stabilizer in its chemistry and is suitable for long-term outdoor use. The product also has a long history of success in hopper lining applications

Industrial Plastics and Custom Colors

A common question we receive is “can I get this in a different color?”. That is tough to answer in the world of industrial plastics! The short answer is many plastics are available in a variety of colors but price, availability, and minimum order quantity (MOQ) are often strongly affected by this choice. In general, industrial plastics are fairly bland, coming in white, black, or a shade of brown. Certain plastics can be colorful, such as nylons and polyurethane, but for the most part they come in black and white.

When Are Colors Feasible?

First of all it never hurts to ask, and we’ll always be straightforward. For the most part; however, we do not stock any plastics in custom colors. This can strongly affect the price if orders need to be brought in on special and in small quantities. Remember that we have to ship product all over North America to “land” it at one of our Regional Sales Offices (RSO). Often, this means you are paying much more for the same plastic just to have a non-standard color. How long you have to wait for delivery is context dependent on your order, but 4-6 weeks would be typical.

Polyurethane, nylon, and some profiles of UHMW are the easiest to get in non-standard colors. Our Redco polyurethane is available in custom colors at no extra cost!

When Are Colors Not Feasible?

The primary barrier to getting a product in non-standard color is when you have to stick to a certain grade of plastic or have a certain additive. For example, we get asked if the anti-static UHMW is available in colors: it is not, because the additive itself makes the plastic black. Also regarding UHMW, “clean” reprocessed UHMW in non-standard colors are much easier to get ahold of in rod or extrusion rather than virgin grade material and a colorant.

Specs given for a product might also confuse requirements. We recently saw a spec for a project that called for black virgin UHMW that was certified to ASTM D4020 but this is impossible as ASTM D4020 specifically excludes UHMW with any and all additives, including color. Natural UHMW is white so a black colored resin, or any additive, automatically cannot meet D4020.

In summary, if you want a non-standard color for your project you need to realize that while it is technically possible you will pay significantly for it in increased cost, delivery, and minimum order quantity.

If you have questions or a request for a non-standard colored plastic – please contact us today.
