We are proud to be a Plastic Manufacturer in the USA supplying Custom Thermoformed parts all over the United States!
Our molds are made in the USA, and our parts are all manufactured from resin made in the United States, as well. Keeping business in the United States is very important, because it strengthens our economy.
At Spencer Industires, we fly our flag with pride!
In 2008 Spencer County’s Population was 20,111. We used this company name because of our involvement with the county. Spencer County is known for it’s beautiful scenery, rolling hills, and fields upon fields of corn. I think the most scenic places to visit would be the St. Meinrad Archabbey and the Lincoln State Park.
Abraham Lincoln lived in Spencer county from 1816 to 1830, between the ages seven and twenty-one. His family moved to Illinois in 1830. The Lincoln Boyhood National Memorial is located at the site of the Lincoln family farm.
You can celebrate history and holidays all year long! Visit Santa Clause, Indiana for information on places to visit in Spencer County.
We posted a quiz last week on opaque plastic. Here are the voting results of optical properties of opaque plastic.
The 2nd answer—Light will not pass through. Cannot be seen through.—is the correct answer.
This is something that is easily confused. Plastic is often classified relative to light penetration because many plastics possess unique properties. There are 4 different types of light penetration. It is much easier to differentiate them when their properties are side by side.
Thermoforming is often a great cost reduction when producing custom products.
Thermoforming methods can be used to reduce cost by eliminating painting and some sub assembly operations. This, combined with the ability to mold in unique geometries that can replace components and additional hardware, are just few ways to cut costs.
Take our Door- In-a Door Refrigerator Door program for example. We used this similar theory in the design stage of the product to produce and improve the Door-In-A-Door program. Spencer Industries worked with the customer to develop a new twin sheet formed version of this product that greatly reduced the number of component parts and the overall cost, while yielding a product that was as aesthetically pleasing and functional as its predecessor.
Twin sheet thermoforming is one of the thermoforming methods that can be used. We chose the twin sheet thermoforming process on this door, which eliminated the sub-assembly of the traditional separate interior and exterior injection molded pieces. Our process allowed us to trap hidden structural components between the two sheets.
This provided a huge savings for our customer!
Feel free to contact us to review your cost cutting needs.
It is our recommendation that each part be discussed prior to and after the quoting process. We have published our Basic Design Guidelines to help you in the design process. We stand ready to assist in these discussions and any questions that may arise.
Materials chosen for a product play a large role in the tolerances of a part. These guidelines are based on experience with dimensionally stable resins, such as HIPS, ABS, and TPO. The guidelines would also not be recommended for dimensionally sensitive materials such as HDPE, HMWPE, PP, and the like.
All trimming is done at ambient plant conditions. Dimensions are based on these temperatures. If parts are measured subsequently in varied temperature conditions, dimensions will change. All materials have differing thermal expansion rates. If wide temperature swings will affect the part it should be noted up front so adequate steps can be taken to ensure that the part will function as designed.
Imagine this could be the last door you ever have to purchase for your box trucks!
This door was designed by Spencer Industries using our twin sheet thermoforming method with a living hinge to reduce hardware cost and assembly. Doors can be made up of as many panels as required depending on the various truck heights. The living hinge door is made from TPO material. This door has been rigorously tested to extreme temperatures and environments, and has proven it could last a lifetime.
Twin Sheet Thermoforming is accomplished by heating of two extruded plastic sheets simultaneously and then forming and sealing or fusing these two sheets together during the thermoforming process. In many cases, the twin-sheeting process produces parts that can resemble a blow-molded or rotational molded product, but with several advantages.
We offer an exceptional team manufacturing exceptional products using vacuum forming, thermoforming, pressure forming and twin-sheeting, and value-added assemblies.
