Frequently asked questions about this product (FAQ)
1. Did it fall off without a few collisions? Is it a quality issue?
The stopper is sintered on the bolt and can absorb the impact force from the front, but when the force point is too inclined towards the side, it is relatively easier to fall off.
2. Will there be any small burrs on the surface after arrival that will affect the use?
It does not affect use. This product is formed by one-time injection molding, and there may be small burrs after molding, but it does not affect use. If there are special requirements for appearance, you can request special production from Mismi customer service.
3. What is the service life of polyurethane gaskets compared to rubber materials?
Generally speaking, polyurethane is more excellent in terms of wear resistance and mechanical strength, with a longer service life. However, polyurethane is more sensitive to changes in the usage environment, especially its hydrolysis characteristics, which can shorten its service life.
4. How can polyurethane and resin heads be used differently? What is low rebound polyurethane?
Polyurethane belongs to the category of elastomers and has better cushioning performance than resin. The material of resin is hard and has much higher mechanical strength compared to polyurethane, which can withstand greater impact forces.
The material of low rebound rubber is very special, which can reduce the thermal energy generated by the workpiece after impact

Indexing plungers are vital mechanical components used to secure, position, and lock movable parts in machinery, fixtures, jigs, and industrial equipment.
In precision machinery and industrial applications, choosing the right mechanical locking or positioning component is critical for reliability, safety, and efficiency. Two common devices used for positioning and locking are indexing plungers and ball lock pins.
Custom indexing plungers are essential components in specialized machinery, industrial equipment, and precision assemblies.
Indexing plungers are essential mechanical components used across various industries to ensure precise positioning, secure locking, and repeatable alignment in machinery, fixtures, jigs, and other adjustable assemblies.
Indexing plungers are essential components in mechanical assemblies, offering precise positioning, locking, and alignment capabilities. They are widely used in machinery, jigs, fixtures, and industrial equipment, where accurate positioning and repeatable movement are critical.
If an indexing plunger starts sticking, failing to seat, or wearing out early, replacing it might "solve" the symptom—but not the cause. Most field issues come from receiving-hole design, alignment stack-up, contamination, or side loading.
In harsh environments, "indexing plunger" is not the full spec. The real spec is: corrosion risk + cleaning method + contamination tolerance + maintenance reality. If you don't design around those, even a premium plunger will feel gritty, stick, or corrode before its expected service life.
"Load rating" sounds simple until a pin bends in the field and everyone asks why. Indexing plunger pins rarely fail from pure axial force. They fail because real assemblies introduce shear, bending, misalignment, and vibration—often all at once.
A standard indexing plunger is designed to re-engage automatically. That's great—until it isn't. In fast changeovers, rotating plates, or safety-critical adjustments, you may need the opposite behavior: the pin must stay retracted until the operator intentionally releases it.
When an indexing plunger "doesn't feel reliable," the issue is often not the plunger. It's the hole. Bore size, chamfer, and engagement depth decide whether the pin finds the target smoothly—or fights burrs, edge damage, and misalignment for the rest of its life.
Did you know that using the wrong set screw can cause permanent damage to delicate components? Whether you're working with polished aluminum, plastic housings, or precision assemblies, a traditional metal set screw might scratch, deform, or even crack your components.
What do medical devices, precision electronics, and high-end furniture have in common? They all require non-marring, precision fastening solutions—and nylon tip set screws are the go-to choice.Standard fasteners often cause more harm than good in delicate assemblies.
Did you know that a single fastener can determine whether your assembly lasts for years or fails within weeks? It's not always about the size or strength of the screw—it's about the application fit. In industries where surface integrity, vibration control, and precision are essential, the nylon tip set screw is often the unsung hero.
"One wrong screw can ruin your entire assembly." That's not an exaggeration—it's a reality many engineers and manufacturers face when choosing between different types of fasteners. Imagine tightening a set screw into a soft aluminum or plastic surface, only to find cracks, scratches, or permanent damage.
In many industries, fastening delicate components without causing surface damage is a constant challenge. That's where nylon tip set screws come in — a smart and reliable solution for non-marring, vibration-resistant fastening.
When you use a sliding door or open a drawer, you can feel the smooth stop and click. This comes from the ball head plunger and spring plunger inside. A high-quality ball head plunger uses strong materials like 304 stainless steel. This gives you better durability and protects against rust.
You use a plastic ball plunger to move parts gently. Material is important. POM and PA work for everyday jobs. PEEK is better for hot or tough places. Ball plungers keep electronics and molds safe. They protect soft surfaces.
Hygiene is very important in food processing. Every part, even a stainless steel ball plunger, must meet hygiene rules. Clean machines help keep food safe for people. Picking parts that resist germs and rust means you can trust your equipment for years.
You use spring ball plunger technology to get steady preload and close tolerances in your automation equipment. Spring-loaded plungers help you get exact positioning. This makes design and performance better.
