Best design Backing Plates | Built-in Heat Management, Smooth Contouring, Perfect for High-speed Polishers

For a car polishing machine performs the best, it needs a reliable backing plate and polishing pad, which collaborate to bring the best result. Polisher, plate, and pad are all separate objects with different types, sizes, and material construction; however, they work together to polish the painted surface under different job requirements and processes.  In this topic, we will dive into details about the MaxShine backing plates and explain why MaxShine brings the best results.  Below is a typical configuration of a polisher, plate, and pad configured for polishing ready.

Professional Polishing Plates

What is a polishing backing plate?

A polishing backing plate is served as a middleman between the polisher and polishing pads. A pad cannot be attached directly to a polisher due to the nature of the polishing pad, which is soft and has to work directly with painted surfaces.   The backing plate needs to effectively transfer the circular or dual-action motion, or both of the actions to the pad while absorbing heat and pressure from the polisher, pad, and polishing action on the painted surface.  In order to transfer the motions effectively, there are several key components associated with the plate to help the smooth power transfer from the polisher.

Backing plate for DA polishers

The backing plate for DA high-speed polishers consists of the main body, polisher interface thread with a bolt, reinforced steel struts, vented holes, and hook and loop fastener, a typical configuration of high-speed DA Polishers. There are variations of the plate configuration to meet specific polisher requirements.  For instance, One of the MaxShine DA Polishers, originally developed for a standard backing plate for M8S V1 / V2 has 6 vented holes while the MaxShine Da Polisher Pro version has 8 vented holes providing better heat absorption ideal for high-speed DA polishers.

The characteristics of the DA Backing Plates

  • Main body material:  The body of the majority of MaxShine polishing backing plates are made of Polyurethane, which is known to be heat resistant and absorb vibration.
  • Thickness:  the thickness of the pro version is 14mm while the other DA polishing backing plates are measured at 10mm.
  • Center hole: a bolt thread to bind the backing plate to a polisher.
  • Thread size: most of the backing plates support 5/16″ thread size for DA polishers, with the exception of the 3″/6″ of M8S / M8 Pro plates.  
  • Reinforced steel struts:  To maintain balance and apply even pressure to the pad, there are 4 or 6 steel struts embedded into the surrounding of the center.

  • Hook and Loop: A hook & loop fastener method is adapted for all the MaxShine backing plates to effectively attach and detach a pad.
  • Tapered Edge:  The tapered edge minimizes direct contact with the surface, helps to smooth contouring, and minimizes air pressure in high-speed orbital motion.
  • The 6 or 8 holes vented design makes easy air flows helping the plate cool and providing thermal endurance.

Backing plates for Rotary Polishers

A rotary polisher works for a job that requires heavy buffing, polishing large areas, and cutting deeper into the painted surface. To meet this demand a backing plate for rotary polishers is different than that of DA backing plates. MaxShine provides 1″, 2″, 3″, 5″, and 6″ backing plates covering most of the possibilities that rotary polishing job needs to be done.

The characteristics of the Rotary Backing Plates

Due to the wider coverage and requiring more cutting power of a rotary polisher, typical rotary backing plates are molded into one piece to endure pressure and powerful circular action. The one-piece design is one of the differences between the DA backing plates and Rotary backing plates.

  • Benefits of Molded One-Piece Design:  The strong molding design allows a large coverage and heavy buffing, easy and safe contouring on the painted surfaces including curves and body lines with high elasticity.
  • High-quality Polyurethane:  The high-quality material construction provides excellent durability and versatility for longevity allowing it to use more than 10000 times.
  • Hook and loop:  The hook and loop fastener makes it easy to attach and replace pads and provides strong bonding.

What is Hook and Loop Fastener for polishing backing plate?

A hook-and-loop fastener, also called the Velcro fastening system,  provides an easy way to attach or detach a polishing pad.polisher backing plates - hook and loop fastener

It is made of nylon, polyester, and polypropylene supplied as woven tapes, reusable over time.  Since a car detailing process requires polishing different areas and shapes, and the depth of targeted polishing areas may vary, frequently, different types of polishing pads are adapted for a certain task.  Thus, the hook and loop fastener is an ideal solution for car polishing.

What are the benefits of polyurethane material?

Polyurethane is used in wide applications in harsh environments proven to be heat and chemical & water-resistive, durable, and strong bonding properties, perfect to be used for a polishing backing plate, which deals with high heat, pressure, and chemicals.

While it provides excellent bonding properties allowing for the integration of thread to the polisher and hook & loop fastener and overall withstanding the harsh polishing operation.polishing backing plate - polyurethane chemical structure

What is tapered edge and how does it help polishing?

A tapered edge is a unique 45-degree slope on a polishing backing plate for reducing air friction while the plate is rotating at high speed helping easy and smooth contouring.polisher backing plates - tapered edge

It also helps to minimize direct contact with painted surfaces when a polisher is leaning toward the surface.


MaxShine brings all the possible dual action and rotary polisher plates that are reliable and meet the specific requirements of buffing jobs. To meet high-quality and efficient polishing results,  MaxShine produces backing plates that are pressure and heat-resistive products through the adaptation of the best material science and structural design.
