FAQ

General Questions

What does BD Custom Manufacturing do?

We extrude custom designed plastics profiles to meet the demands of the manufacturing industries.

What types of plastic do you extrude at your Bristol facility?

In order to produce a quality product and meet the price demands of each industry, we have chosen to work PVC and Polyethylene. We find these to be two of the best thermoplastics for our process.

What industries does BD Custom Manufacturing extrude for?

Because we are a custom shop, we are not limited to a specific product line or industry. We extrude parts for the marine, appliance, construction, RV and furniture markets to name just a few.

What colors are available for extruded plastic profiles?

Although most extrusions are requested in black, white or grey, the rainbow is our pallet. We will review the profile as well as the color to determine if a minimum run will be required. To see a few examples of our color capabilities.

What is the lead time required for my order to be completed?

When your profile is to be extruded in one of our 50+ stock colors, our standard lead time is usually ten working days from the time that we receive an order accompanied with a usable die.

What if I need my extruded plastic parts tomorrow?

We know that emergencies arise, so we each week, we schedule our PVC and Polyethylene extrusion production to accommodate the needs of our clients.

Can you deliver my plastic extrusions order or do I need to pick it up?

Our trucks leave the plant each morning so that our courteous drivers can reach your plant with on-time deliveries. If you prefer, you are always welcome to pick-up your custom plastic extrusions order in our midwest office located in Bristol, IN, where you will be greeted with professional and friendly service. We also custom package our product for those who require the use of common carrier.

Quality Control

What is the BD Custom Manufacturing stance on Quality Control?

If you have ever been placed in a position of using faulty parts because you could not wait for a replacement run, you will appreciate the BD Custom commitment to Quality Control.

We are focused on the customer; large, medium and small. We operate our business with a system that creates and implements a continuous improvement process that produces results that will exceed our customers expectations.

We achieve our objective by random inspections , systemmatic data collection and analysis and other tools which are used to understand and improve our processes. Our Quality process begins at the receiving dock and follows all of the way through production, packaging and shipping. If a problem arises in meeting the specifications outlined in our detailed prints, that problem is confronted and corrected, and we are back in production for timely delivery. This fully protects you from the warranty and manufacturing dilemmas that are presented when you are forced to stop your production line or to make something work. BD Custom Manufacturing is committed to providing our customers with on time delivery of quality parts.

How will I know that my part will fit correctly?

Our process follows a strict quality control procedure to meet the specifications outlined in the drawings provided? We maintain a set-up manual for each profile and follow all of the guidelines set forth to confidently guarantee the fit and function of each profile that we extrude.

Tooling

Do I need different tooling for a Vacuum Calibrated product?

Many improvements in tooling have been introduced in recent years. Vacuum tooling differs from standard plastic extrusion tooling in that it is built with channels to create a path for air (vacuum) and a series of ducts to allow for the flow of coolant.

PVC, Polyethylene and most thermoplastic resins are assisted by a vacuum that is applied to the external surface of the extruded profile while it is drawn through a calibrating tool. During this step, the profile is formed and the surface of the extrusion is cooled indirectly by water flowing through channels in a calibrating tool.

This process is most often used for tubular extrusion, where the key issue is the assurance of roundness. It is also used when a true 90 degree angle must be maintained. This entire process is often referred to as vacuum calibration.

Do I need to supply BD Custom with tooling to make my parts?

No. If you already own your dies, we will see if we can adapt them for our equipment, however, the best approach would be to supply us with a detailed drawing of the part to be extruded.

Vacuum Sizing

What is vacuum sizing?

Vacuum sizing is the term given to the use of calibrated vacuum pressure to help form a consistent plastic part that will meet the specifications of the extruded component.

Is vacuum calibration tooling something new?

Vacuum calibration tooling has been used in the manufacture of plastics since the 1950s, however, many improvements in tooling have been introduced in recent years. The tooling is built with channels to create a path for air (vacuum) and a series of ducts to allow for the flow of coolant. PVC, Polyethylene and most thermoplastic resins are assisted by a vacuum that is applied to the external surface of the extruded profile while it is drawn through a calibrating tool. During this step, the profile is formed and the surface of the extrusion is cooled indirectly by water flowing through channels in a calibrating tool. This process is most often used for tubular extrusion, where the key issue is the assurance of roundness. It is also used when a true 90 degree angle must be maintained. This entire process is often referred to as vacuum calibration.

Can you make sure that there will not be thin spots in my plastic parts?

Yes we can. During the manufacturing process, air can be applied to force the heated and now softened plastic along the walls of the profile tooling. The air is set at different pressure levels during this stage of the process to assure that dimensional specifications are met within the wall of the extruded part. As the extrusion is leaving the profile tooling, air is also applied in the form of a vacuum to maintain the shape as well as the correct specifications of the part. We take important care in our QC procedure to maintain the proper equipment speed, tooling temperature, vacuum pressure and cool down procedure which are all vital to making a functional extrusion.
