How to Clean Molded Plastic Parts for a car: (Plastic Molding Techniques 2020)

In the production of vowin.cn/' target='_blank'>molded plastic parts, contraction is very important. And we must consider it carefully, as it will reflect on the dimensions of the molded product. Moreover, it will influence the following important injection items:

• The solidity that the contraction can cause, in points of the product with different thicknesses, tensions that can cause cracks, ruptures, etc. Due to dimensional instability, the contraction may not be uniform across the surface of the molded part. Hence, it will cause warping and deformation. This usually happens in parts that have different thicknesses in various parts. They consequently do not undergo uniform contraction.
• Insert of metal parts, where the contraction of metal is different from that of plastic. This, when cooled, can contract two to five times more than metals. Consequently, the force of this contraction acting on the metal. It has greater mechanical resistance, may cause the molded plastic partsto break.
• The dimensional tolerances obtained according to the plastics contraction coefficient are not always constant. Furthermore, they depend on several factors, such as: inconsistency of the properties of the raw materials used in their preparation, etc. The average tolerances adopted to determine the dimensions of a part must not be less than a given limit.

Important molded plastic parts Precautions

When creating injection projects, we must pay attention to many other characteristics of creating this tool. Because in addition to the physical components that make up the assembly, many other data and techniques must be used in the projects.

• Closing panels that block unpleasant mechanical parts
• Molded plastic parts, such as door panels, for easy assembly
• Smooth and painted components, such as bumper covers and interior finishes
• Soft-touch plastics for attractive interior finish
• Textured molded plastic parts

Plastic components can get dirty, as can the rest of your vehicle. It may be dust, oils or even food or drinks that remain in the plastic. Plastic may need to be treated differently from other parts, depending on its composition and finish.

Method 1: Cleaning Internal molded plastic parts

The interior of your car is significantly more protected from the environment than the exterior. Typical problems that occur with the inner plastic are:

• Cracks
• Dust accumulation
• Dirt

Once a molded plastic parts is broken, you will not be able to restore it to its previous condition. You can, however, treat your interior plastic to prevent most cracks and deterioration while you clean your car’s interior plastic. Look for a high quality cleaning product that also conditions the plastic.

Tip: Car wipers that leave an oily shine may look good initially, but they collect dust and dirt quickly. Use a cleaning product that does not have an oily feeling or shine after use.

Necessary materials

• Indoor cleaning product
• Detail brush or toothbrush
• Foam applicator pads
• Lint-free cloths or microfiber cloths

Molded Plastic Parts Tips

Step 1: clean the dusty surfaces. Use a lint-free cloth to clean all the inside of your car.

You are looking to remove most of the dust and dirt, so that the end result is cleaner and scratch-free.

If the surfaces are very dirty, you can use a damp cloth to absorb more dirt initially.

Step 2: Spray the plastic cleaner over a foam applicator. If you spray directly on parts like the dashboard or the door panel, the fog will settle on the windows, making you work harder to clean the car later.

Place the applicator moist with the cleaner.

Step 3: Clean the inner plastic with the cushioned applicator.

Work with one area at a time. If you are cleaning the panel, clean it thoroughly with the cleaner and proceed to the next step.

Step 4: Clean the molded plastic parts trim with a lint-free cloth. This will remove most of the moisture and leave a clean, dust-free surface.

Repeat for each plastic area.

Step 5: Clean dirty cracks . There are seams and crevices wherever plastic parts meet another surface. Dirt accumulates in these areas frequently, making a clean car look a little sloppy.

• Dip the detailing brush into the plastic cleaner or spray the brush with the cleaner.
• Work the brush bristles or a Q-Tip into the slot in a forward and backward motion.
• Take the dirt and cleaner you brush with a cloth.
• Wipe deeply into the slot with the cloth to absorb any remaining cleaner.

Tip: Transparent plastic parts, such as the instrument panel or radio screen, are best cleaned with glass cleaner, just like windows.
