Cracked plastic parts can be frustrating because glue alone often fails when the repair area bends, twists, or takes impact. The 1400 Plastic Welder Staples set is made for hot staple plastic repair jobs where you need reinforcement across the damaged area. This set includes 700 pieces of 0.6mm wave staples and 700 pieces of 0.8mm wave staples, giving you two thickness options for different repair needs. It is a practical choice for automotive and home plastic repairs, but you should confirm that the staple shape and size work with your plastic welder gun before buying.
Quick Verdict
Rating: 8.2/10, Recommended with caveats
Best For: DIY users, auto trim repair, bumper repair practice, and small home plastic repair projects.
Bottom Line: This 1400-piece staple set gives you a large supply of stainless steel wave staples in two useful thicknesses. The main tradeoff is compatibility, since these staples still need a suitable plastic welder gun and correct placement to work well.

What Are the 1400 Plastic Welder Staples?
The 1400 Plastic Welder Staples set is a refill assortment for plastic repair work. Instead of acting like glue, these staples are heated by a compatible plastic welder gun and pressed into the damaged plastic to reinforce a crack from the inside.
The set includes two staple thicknesses: 0.6mm and 0.8mm. That matters because thinner staples can suit smaller or more delicate repair areas, while thicker staples can help when the damaged plastic needs more reinforcement. The supplied article also describes these as wave staples, which are commonly used when you need grip across a crack line.
This set makes the most sense if you already own a compatible plastic welder gun or plan to buy one separately. The staples are not a complete plastic repair kit by themselves, so they are best viewed as refill consumables for repeated plastic repair work.
Before You Buy: These staples are not a standalone repair tool. You need a compatible plastic welder gun, correct heat control, and enough access behind or across the crack to place the staples safely.
Who Should Buy It?
Best For
- DIY users who repair cracked automotive plastic, bumper tabs, trim pieces, or plastic panels.
- Home repair users who want a large refill supply for compatible hot stapler tools.
- Workshops that go through staples often and need both 0.6mm and 0.8mm options.
Skip If
- You do not own, or do not plan to use, a compatible plastic welder gun.
- You need staples in a different shape, size, or thickness for your specific repair tool.
- You want a cosmetic-only repair with no visible finishing work after the staple is installed.
Product Features and Specifications
The biggest strength of this set is quantity. With 1400 total pieces, you get enough staples for practice, multiple repair attempts, and larger jobs that need several reinforcement points along one crack.
The split between 0.6mm and 0.8mm staples also gives you more flexibility than a single-size pack. You can use the 0.6mm staples where you want a lighter touch and reserve the 0.8mm staples for repair areas that need stronger reinforcement.
The article describes the staples as stainless steel. That is useful because plastic repair staples need to hold their shape, resist twisting, and remain stable after they are embedded into the repair area. Still, the final repair strength depends on the plastic type, staple placement, welding depth, and how well you finish the surface afterward.
Materials and Build Quality
These staples are designed for reinforcement, not surface bonding. Once heated and pressed into plastic, the metal bridge helps hold the cracked area together from within the material.
The stainless steel construction is a practical choice for automotive and home repair settings because the staples may face vibration, flex, and handling stress. The supplied article also notes resistance to shock and twist, which is useful for parts that move slightly during normal use.
The pre-cut design is another useful detail. After welding, you can remove the excess ends more easily, which helps you prepare the area for sanding, trimming, or finishing. You still need to work carefully because cutting or twisting the staple ends too aggressively can damage the surrounding plastic.
Fit and Compatibility
The article states that these staples are compatible with plastic welder guns, but you should still check your tool before ordering. Plastic welder guns may use different staple shapes, wire thicknesses, and insertion slots.
For best results, compare your current staples or your tool manual with the 0.6mm and 0.8mm wave staple sizes in this set. If your gun requires flat, V-shape, M-shape, or outside-corner staples, this wave-style assortment may not cover every repair situation.
This product is best for users who already know that wave staples work with their plastic welder. If you are buying your first hot stapler, it may be safer to start with a complete kit that includes both the tool and several staple types.
Application and Usability Insights
For plastic repair work, placement matters as much as staple quality. The staple should bridge the crack, sit at a useful depth, and avoid pushing through the visible side of the part.
The 0.6mm staples may be easier to control on thinner plastics. The 0.8mm staples can be better when the damaged area needs more support, but they may require more care on thin or brittle plastic.
The article mentions use on plastics such as ABS and PVC. Those materials can appear in automotive and household applications, but plastic types vary widely. You should test on a hidden area when possible and follow the settings recommended for your plastic welder gun.
Pro Tip: Start with fewer staples and add more only where the crack still flexes. Too many staples in a small area can weaken thin plastic or make finishing harder.
How It Performs in Real Use
For Automotive Plastic Repairs
This staple set is well suited for common automotive plastic repair tasks where a crack needs extra backing strength. It can help with bumper tabs, trim pieces, brackets, and similar plastic parts when the damaged area can accept a hot staple repair.
For Home Plastic Repairs
For household plastic items, the large 1400-piece count gives you room for small repairs and practice attempts. The staples can help reinforce cracked plastic housings, bins, panels, or other repairable plastic parts, as long as the plastic can handle the welding process.
For Practice and Learning
If you are new to plastic welding, the large quantity is helpful because early attempts may not be perfect. You can practice on scrap plastic before working on the part you actually need to fix.
For Long-Term Workshop Use
For users who already repair plastic often, the two-size assortment reduces the need to buy small refill packs repeatedly. The main limitation is that this is still only a wave staple set, so you may need other staple shapes for corners, tight curves, or specialty cracks.
How to Use These Staples Correctly
Before you start, clean the repair area and make sure the plastic is dry. Dirt, grease, and loose fragments can weaken the repair or make the staple sit unevenly.
Choose the staple thickness based on the plastic and the crack. Use lighter pressure on thin plastic and avoid holding heat in one spot too long. The goal is to embed the staple securely without burning through the surface.
After the staple cools, remove the excess ends carefully. Then inspect the repair before sanding or finishing. If the crack still moves, you may need another staple, but spacing matters. Crowding staples too close together can create new stress points.
Compatibility and Safety
Plastic welding involves heat, metal staples, and fumes from heated material. Work in a ventilated area, wear eye protection, and keep your hands away from the heated staple and tool tip.
Do not use these staples on plastic parts where a failed repair could create a safety risk unless you know the repair method is appropriate. For load-bearing automotive parts, safety-critical brackets, or structural components, consider professional repair or replacement.
Also remember that not every plastic responds the same way to heat. Some plastics soften cleanly, while others can burn, deform, or release stronger odors. Always follow your tool instructions and test carefully when you are unsure.
Pros and Cons
Pros
- Large 1400-piece count supports repeated repairs, practice, and workshop use.
- Includes both 0.6mm and 0.8mm wave staples for different repair needs.
- Stainless steel construction supports durable plastic crack reinforcement.
- Pre-cut design helps with easier removal after welding.
- Useful for automotive and home plastic repair projects when used with a compatible tool.
Cons
- Requires a compatible plastic welder gun, which is not described as included.
- Wave staples may not suit every crack shape, corner, or tight repair area.
- Repair quality depends heavily on heat control, placement, and the plastic type.
Is It Worth the Price?
This set offers strong value for the price if you already use a plastic welder gun and need a large supply of staples. The 1400-piece count makes it better for frequent repairs than small packs that run out quickly.
It is worth considering if you repair automotive plastic, workshop parts, or household plastic items often. You get the most value when both included sizes match your tool and your repair style.
It is not the best fit if you need a complete plastic welding kit, a brand-specific refill, or several staple shapes for specialty repairs. In that case, compare the shape and size requirements before you buy.
How It Compares to Alternatives
Compared with smaller refill packs, this set gives you more quantity and two staple thicknesses, which helps if you repair plastic often. Compared with complete plastic welder kits, it is more limited because it does not replace the tool itself.
If you need different staple shapes for corners or complex cracks, a mixed-shape assortment may be better. The 1400 Plastic Welder Staples set makes the most sense when you specifically want a large supply of 0.6mm and 0.8mm wave staples.
Frequently Asked Questions
Are these staples compatible with all plastic welder guns?
No. The article says they are compatible with plastic welder guns, but you should still confirm your tool accepts 0.6mm and 0.8mm wave staples. Check your welder manual or compare the staple shape with the staples you already use.
What do the 0.6mm and 0.8mm sizes mean?
The sizes refer to the staple thickness. The 0.6mm staples can be useful for lighter plastic repairs, while the 0.8mm staples may add more reinforcement for tougher repair areas.
Can you use these staples for car bumper repairs?
Yes, they can be used for automotive plastic repair when the plastic type and repair location are suitable for hot staple welding. For safety-critical or structural damage, a professional repair or part replacement may be the better choice.
Can these staples be used indoors and outdoors?
They can support repairs on indoor and outdoor plastic items, but the finished repair depends on the plastic, the welding quality, and the stress on the part. Outdoor parts may also need finishing or sealing to protect the repaired area.
Do these staples replace glue or epoxy?
They can reduce the need for adhesive in some repairs because they reinforce the crack mechanically. Some repairs may still need surface finishing, filler, or adhesive depending on the part and appearance goal.
How should you store unused plastic welder staples?
Store unused staples in a cool, dry place where they stay clean and organized. A small parts box or sealed container can help prevent moisture exposure and make it easier to separate the 0.6mm and 0.8mm sizes.
What safety precautions should you follow?
Wear eye protection and heat-resistant gloves, and work in a ventilated area. Keep the hot staple and tool tip away from skin, wires, fuel, solvents, and other flammable materials.
The Bottom Line
The 1400 Plastic Welder Staples set is a smart buy for users who already have a compatible plastic welder gun and want a large supply of 0.6mm and 0.8mm wave staples. Its main strengths are the high piece count, stainless steel construction, and pre-cut design, while its main limitation is that compatibility depends on your repair tool and repair situation. Skip it if you need a full plastic welding kit or a mixed-shape assortment for more complex cracks.
