These shears make precise cuts and have comfortable handles, which help achieve clean edges in polycarbonate sheets.
PVC Sheet Cutting Shears
PVC sheets are widely used in construction and plumbing. The material is known for its resistance to moisture, chemicals, and corrosion. PVC sheet cutting shears have sharp, durable blades designed specifically for cutting PVC pipes and sheets. They work best when cutting thick, rigid sheets and leave a clean, smooth edge. Some types of PVC sheet cutting tools are also suitable for cutting other materials, such as copper, aluminum, wood, and rubber.
Styrene Cutting Shears
Styrene is an affordable plastic used to make home appliances, toys, and models. Styrene cutting shears are designed to cut styrene sheets or rods. They have sharp blades that produce smooth cuts on styrene without fraying or cracking the material. The shears' lightweight and easy-to-use feature is ideal for hobbyists and model builders.
Formed Plastic Cutting Shears
Formed plastics are three-dimensional and cannot lie flat on a table. They are often used to make automotive parts, cash register housings, and medical equipment. Formed plastic cutting shears are specifically designed to cut these 3D plastics. They have long, thin, and angled blades that move past each other to make precise cuts in tight or limited access areas.
Size and Thickness of the Sheet:
The size and thickness of the plastic sheet determine which shear will do the job. For smaller and thinner sheets, regular household scissors may work. But for larger and thicker sheets, heavy-duty shears designed for cutting thick materials are needed.
Type of Plastic:
The type of plastic determines the cutting ease and finish. Some plastics, like acrylic, are more rigid and require special shears with a fine cutting edge to avoid chipping. Others, like polyethylene, are flexible and can be cut with regular scissors.
Desired Cut Quality:
The desired cut quality affects which shears to use. For rough cuts, heavy-duty shears or power tools like a jigsaw may be used. For smooth, finished edges, special plastic cutting shears with a serrated edge or fine scissors are better.
Budget:
How much needs to be spent on cutting tools? Budget affects which shears or tools are purchased. Power tools are more expensive but may be needed for large, thick sheets. Manual shears are cheaper and work for smaller, thinner sheets.
Ease of Use:
Consider how easy the chosen shear or tool will be to use. For large sheets, power tools may be easier than manual cutting. Look for features that make cutting comfortable, like ergonomic handles or a lightweight design.
How to use
Plastic sheet cutting shears are essential tools for crafters and DIY enthusiasts. Here are instructions on how to use them to get a precise cut on plastic sheets:
Prepare the Work Area:
Ensure the work area is clean and clutter-free. Gather all necessary materials, including the plastic sheet, cutting shears, ruler or measuring tape, cutting mat or board, and any marking tools.
Measure and Mark:
Use the ruler or measuring tape to measure the desired length or width of the plastic sheet. Mark the measurements clearly with a dry-erase marker or masking tape, ensuring the lines are straight and visible.
Prepare the Plastic Sheet:
If the plastic sheet is flexible, place it on the cutting mat or board. This will prevent the sheet from bending and provide a stable cutting surface.
Open the Cutting Shears:
Grip the plastic shears firmly with one hand and open them by spreading the handles apart. Ensure the cutting edges are aligned and facing each other.
Position the Plastic Sheet:
Bring the cutting shears close to the marked line on the plastic sheet. Position the cutting edge of the shears flush against the edge of the sheet for a clean cut.
Begin Cutting:
With the plastic sheet firmly held in place, squeeze the cutting shears handles together in a smooth, controlled motion. Apply even pressure as one handle moves toward the other. Repeat the squeezing motion to cut through the sheet.
Follow the Marked Line:
As the cutting shears approach the end of the sheet, maintain focus on the marked line. Stop squeezing the handles when the cutting edge reaches the line, and allow the shears to complete one final squeeze.
Complete the Cut:
Release the handles of the cutting shears and lift them away from the cut plastic sheet. Inspect the cut edge for smoothness and precision. If necessary, use sandpaper or a file to refine the edge further.
Product Safety
When using plastic sheet cutting shears, it is important to follow certain safety measures to avoid injury or damage to the plastic sheet. Here are some safety tips:
Protective Gear:
Always wear safety goggles when cutting plastic sheets to protect your eyes from flying debris. Consider wearing a dust mask if cutting large sheets to prevent inhaling fine plastic particles.
Cutting Surface:
Use a sturdy cutting board or mat beneath the plastic sheet to protect your work surface and provide stability during cutting. This will also prevent the sheet from slipping or moving while cutting.
Sharp Edges:
Be cautious of sharp edges when cutting plastic sheets, as they can cause injury. Use shears specifically designed for cutting plastic, as they have safety features that reduce the risk of cuts. Check that the cutting edges are aligned and not damaged before use.
Proper Grip:
Hold the plastic cutting shears firmly by their handles while cutting to maintain control and prevent accidents. Keep fingers clear of the cutting blades and do not place them near the edge of the plastic sheet being cut.
Cutting Technique:
Use smooth, controlled motions when cutting the plastic sheet, and avoid forcing the shears through the material, as this can cause the plastic to bend or warp. Instead, make several slow, deliberate cuts to achieve a clean edge.
Cutting Line:
Follow the marked line when cutting the plastic sheet to ensure a straight and precise cut. If necessary, use a straight edge or ruler as a guide to achieve a clean edge.
Cutting Plastic Sheets:
These shears can easily cut thin plastic sheets, such as those used in crafts, home improvement projects, or model building. Their design allows for clean cuts without jamming or bending the material.
