Removing plastic rivets

Types of removing plastic rivets

Removing plastic rivets is a common practice in various industries, especially in automotive and construction, where plastic fasteners are used to hold parts together. Plastic rivets, also known as plastic clips or push-fit fasteners, come in different types, and knowing how to remove them is crucial to avoid damage to the material they're holding. Here are some common types of plastic rivets and how to remove them:

• Push-in rivets

  Push-in rivets are one of the most common types of plastic rivets. They are fast and easy to use, making them ideal for applications that require quick assembly and disassembly. A typical application is attaching car door panels to the body. To remove push-in rivets, a flathead screwdriver or trim removal tool is inserted under the head of the rivet. Then, gentle prying lifts the head, and the body of the rivet is pulled out from the underneath.

• Screw-type plastic rivets

  As the name suggests, screw-type plastic rivets resemble screws. They have a threaded shaft that screws into a mating part, providing a secure and tight fit. They are commonly used in assembling electronic housings and other plastic parts. To remove screw-type plastic rivets, an appropriate-sized screwdriver is used to unscrew them. Turning counterclockwise loosens the rivet, and once it is free, it is lifted out of the hole.

• Clips and clamps

  These plastic rivets are used to secure cables, hoses, and other components along a path. They are used when parts need to be held together without drilling holes into the substrate. To remove clips and clamps, a suitable tool, such as pliers or a clip removal tool, is used to open or stretch the clip or clamp. Then, it is slid off the cable or hose and away from the mounting surface.

• Expansion rivets

  Expansion rivets are designed to be inserted into pre-drilled holes and expand behind the panel or substrate to create a strong fastening point. They are commonly used in attaching body kits or trim pieces to vehicles. To remove expansion rivets, a suitable tool is used to push the center pin inward, collapsing the expanded legs. This loosens the rivet, and it is carefully pulled out from the front.

• Retaining clips

  These plastic rivets are used to hold shafts, pins, and other components in place to prevent unintended movement or disassembly. They are used in applications such as suspensions, steering columns, and drivetrain assemblies in automotive applications. To remove retaining clips, a circlip plier or clip removal tool is used to open the clip. Then, it is pried off its groove or mounting location.

Specifications and maintenance of removing plastic rivets

Here are the specifications and maintenance requirements for removing plastic rivets.

• Specifications

  Plastic pop rivet guns are available in different sizes and specifications. Here are some common specifications:

  1. Grip Range: This is the thickness of materials the rivet gun can hold together. It is usually measured in mm or inches. A rivet gun with a large grip range can work on thicker materials and vice versa.

  2. Rivet Size Capacity: This is the range of rivet sizes the gun can install. It is usually measured in mm or inches, just like the rivet size. A gun with a larger rivet size capacity can install larger rivets.

  3. Force: Plastic rivet guns generate different amounts of force. The force is measured in pounds or Newtons. A rivet gun with more force can install larger rivets or work on thicker materials.

  4. Length and Weight: Plastic rivet guns are available in different lengths and weights. Generally, rivet guns are portable and lightweight for ease of handling.

  5. Construction Material: The material used to manufacture a plastic rivet gun determines its durability and strength. Common construction materials include carbon steel and aluminum.

• Maintenance

  1. Inspect the rivet gun regularly for worn-out or damaged parts and replace them immediately to prevent accidents.

  2. Clean the rivet gun after use to remove dirt, dust, and debris. Also, lubricate it regularly to ensure it operates smoothly.

  3. Store the rivet gun in a dry place away from children and direct sunlight. Avoid dropping the gun or exposing it to extreme temperatures.

  4. Use the tool correctly as per the manufacturer's instructions. Do not overload or misuse the gun, as this can cause damage.

How to Choose Remo

• Understanding the project requirements

  Before choosing a tool for removing plastic rivets, understand the project requirements. Find out the type of plastic fasteners used in the project and their locations. Also, determine the number of rivets to remove. This will help choose the right tool for the job.

• Consider the condition of the surrounding materials

  Consider the condition of the surrounding materials before removing plastic rivets. If the surrounding materials are old or fragile, use a less destructive approach. This involves using hand tools like prying and lifting. Avoid using power tools that may damage the surrounding materials.

• Choose the right technique

  There are various techniques for removing plastic rivets. These include cutting, prying, and drilling. Choose a technique that will cause minimal damage to the plastic parts and surrounding materials. Also, choose a technique that will remove the rivet quickly and easily.

• Prepare the work area

  Prepare the work area before removing plastic rivets. Clear the area of any clutter and remove any sensitive equipment or materials. This will create a safe working environment and reduce the risk of damage to surrounding materials or personal injury.

• Wear protective gear

  Always wear protective gear when removing plastic rivets. This includes gloves, safety glasses, and masks. The rivet removal process can involve cutting or drilling, which poses risks of injury. Also, some plastic fasteners may contain hazardous materials that require protection when handling.

• Follow manufacturer instructions

  If possible, follow the manufacturer's instructions when removing plastic rivets. Locate the service manual or user guide for the equipment or vehicle. This will provide the best methods and techniques for removing the specific type of plastic rivets used.

• Plan for reinstallation

  If the project requires reassembling or replacing the plastic parts, plan for reinstallation. Choose a rivet removal technique that makes reinstallation easy and consider the type of fasteners to use during reassembly.

How to DIY and Replace Removing Plastic Rivets

Some essential tools that are required to remove plastic rivets are as follows:

• Rivet removal tool: This is a specialized tool that is used for removing rivets.
• Screwdriver: A screwdriver is used in removing plastic fasteners.
• Pliers: Pliers are used in removing melted rivet stems.
• Drill: A drill is used as a last resort when removing stubborn rivets.
• Trim removal tool: This tool is used for safely prying up trim pieces without causing damage.

Follow the steps below to remove plastic rivets:

• 1. Identify the rivet type: Different types of plastic rivets are available. Identifying the type will help in knowing how to remove it.
• 2. Examine the access point: This involves checking how the rivets can be accessed and knowing the type of tool that is required.
• 3. Prepare the work area: This involves removing nearby components that may obstruct the removal process.

Q&A

Q1: Why are plastic rivets used?

A1: Plastic rivets are used to fasten plastic parts together. For example, they are used to attach door panels to the car body. Plastic rivets are preferred in such applications because they do not corrode.

Q2: Can one reuse plastic rivets?

A2: It is not advisable to reuse plastic rivets. During the removal process, the rivets may get damaged. Even if they are not damaged, they may not secure the parts properly when reused.

Q3: What is the difference between metal and plastic rivets?

A3: Metal rivets are suitable for heavy-duty applications. They provide a permanent fastening solution and are used to join structural components. On the other hand, plastic rivets are used to fasten lightweight plastic parts. Plastic rivets are preferred in applications where corrosion resistance is required.
