Leading Plastic Trim Manufacturers

Plastic trims are items that do not change the functionality of the structure or machine when added; rather, they enhance the aesthetics with lightweight plastic materials. They are extruded to make any shape depending on the design of the material to be trimmed. Plastic trims can hold, attach, and seal, which makes them suitable for many applications. Many types of plastics can be used for making trims depending on the application, PVC being the most common. Read More…

Plastic trims are used in many industries; for example, the motor industry for door pockets, consoles, seats, dashboards, and door seals. Trim is also used for the exterior and interior fenders and the construction industry for door frame insulation, window insulation, outdoor/indoor siding, bumpers, and protection on sharp edges and corners.

In addition, plastic trim is used in the furniture, leisure, and marine sectors for various purposes. Manufacturers mainly use flexible vinyl and PVC trim for microwave ovens and stove seals doors. Edge trim, internal ornamental trim, fender flare trim, U trim, drip rail trim, lip trim, and J trim are popular varieties of plastic trim.

How Plastic Trims Are Made

The technique used in molding a plastic profile of trims is straightforward. First, a high-volume manufacturing process called plastic extrusion is used, where a polymer material is continually melted and molded while enriched with the desired additives. Additives help improve the plastic trims' chemical and physical properties to suit a certain application.

There are many additives for different functions; for example, additives to change appearance, increase strength, make plastics lighter, make plastics safer, make plastics more eco-friendly, and make better products. In manufacturing plastic trims, the extrusion method is used. This allows a continuous way of producing trims. Then, with the help of gravity, the feed, the plastic granules, is added to the hopper of the screw extrusion machine as the raw thermoplastic material.

The rotating power of the machine is provided by the induction motor coupled to the screw using the rotating shaft and bearings. The feed reaches the rotating screw and is conveyed through the heated burel. Three or more separate proportional integral derivative (PID) controllers are used to produce zones that continuously raise the heating temperature of the barrel. By so doing, the state of the plastic is changed from a solid state to a semi-solid state, which helps in better mixing the plastic raw materials and, in the process, removing the air bubbles.

The molten plastic is continually passed through a two-dimensional die after heating and is then supplied as several blocks. Typically, the temperature is higher than the melting point of the plastic selected for the PID controllers. Shear friction (shear heat) and compressive force will also produce additional heat, which can be added to the production process. The molten plastic is thoroughly mixed when it reaches the screw's end.

It is then forced through a screen pack supported by a breaker plate to sieve contaminants and remove the material's rotational memory. The molten plastic that has been purified is then forced through the die. The completed plastic trim receives the necessary profile and shape thanks to the die. Finally, the plastic trim is taken from the extruder and chilled.

Manufacturing Process

Using the extrusion method in the manufacturing process, several steps are followed:

Step 1: Plastic Extrusion and Molding

Using the screw conveyor method, the plastic feed is heated and compacted to the walls of the die, producing the desired shape and size.

Step 2: Cooling

Since the molded trim has a high temperature, the extruded plastic trim is cooled in a cooling solvent.

Step 3: Spool or Cut

The cooled trim is then cut into desired shapes and sizes.
