Flame retardants (FR) are chemical compounds designed to inhibit or delay the ignition and combustion of polymeric materials. To effectively prevent fire propagation, it is essential to develop thermally stable polymer structures that exhibit low decomposition rates and reduced generation of combustible gases under elevated temperatures. In recent years, the demand for a...

In the world of bolt assembly, we often focus on the torque value – that clearly visible number on the wrench. Engineers strictly set the torque according to standards, and operators accurately perform the tightening. However, a hidden "controller" plays a decisive role behind the scenes: the friction coefficient. Many mistakenly believe that "tightening" is everything,...
1. What is Annealing Annealing is a heat treatment process applied to metals (and sometimes other materials) in order to alter their physical (and sometimes chemical) properties. The main goal is to increase ductility and toughness, reduce hardness, relieve internal stresses, and restore work-hardened metals to a more workable, stable state. 2. The Basic Steps and Mec...
The main job of a screw is to “fasten things together”. But it's a wonder that you can fasten things together just by turning and screwing it in, isn't it? Actually, every shape of a screw has a meaning, and it is a condensation of many wonderful technologies! For a detailed explanation of screw fastening, see here There is another important role that screws play. That ...
There are various factors such as the shape of the head, the shape of the drive unit, the shape of the threaded part (helix), and the material, and there are as many as 90,000 types of screws manufactured by NITTOSEIKO.

Choose a matching screwdriver bit to ensure it can firmly grip the screw, reducing the possibility of slipping or deviation. Magnetic bits can also be used to help stabilize the screw and prevent it from tilting at the start of tightening. II. Preparation Work Screw Surface Treatment: Ensure the surface is clean and free of dust, grease, or other impurities, as these c...
The accuracy of a tightening tool directly determines how precise and stable the torque output is, and is therefore the key indicator for guaranteeing joint quality. Yet when we evaluate a tool’s accuracy we often meet two seemingly similar terms – 6σ and ±3σ. Can you clearly distinguish them? And what is the critical difference? The concepts of 6σ and ±3σ – two ways o...
In the world of metal assembly, “torque control” is the undisputed golden rule: we set a target torque, the tool stops when it reaches that value—simple, direct, effective. Yet when we copy this strategy verbatim to the case of driving self-tapping screws into plastic parts, trouble usually follows: either the screw is “floating” (not fully seated) or we over-do it and s...
In today's industrial production landscape, automation equipment is gradually becoming a key driver in enhancing production capabilities. Among these, robotic bolt tightening—thanks to its notable advantages—is being widely adopted across assembly processes in various industries. Whether in electronic component assembly, automotive parts production, or large-scale equipm...

In high-precision assembly scenarios such as engine cylinder heads and transmission housings, it's common to see this scene: after an intelligent electric screwdriver tightens a screw to the target torque, it doesn't immediately withdraw. Instead, it holds that state for a few seconds. This seemingly "redundant" action is actually a critical factor in determining whether...
In modern industrial production environments, multi-product co-line production has become a common model. For electric screwdrivers, frequently switching tightening parameters for screws of different specifications has always been a challenge affecting production efficiency. Traditional screwdrivers require a significant amount of time to reconfigure tightening parameter...
In industrial production, driving screws is a common yet critical operation; tightening quality directly affects product quality and safety. However, when operators make mistakes or when the process is not standardized, the same bolt is occasionally tightened twice, introducing various risks. To cope with this problem, making use of the advanced functions of a smart elec...

What is a self-tapping screw? In the usual sense, a self-tapping screw is a threaded fastener that does not need a pre-tapped internal thread. When the screw is driven into a smooth, untapped hole, it cuts its own internal thread, so a relatively high torque is required. The mating part is normally a soft material such as plastic or an aluminum/magnesium alloy. Self-tap...
In most mechanical products, screw fastening is the commonest way to join parts. TV sets, mobile phones, cameras and other electronic devices use large quantities of screws whose nominal diameter is below 5 mm, and “screw float” (the head stands off the surface) is a frequent defect. Float can irreversibly damage the threaded boss or the PCB, so lock-quality control must...
In automated screw-assembly lines, the single-cycle time required to deliver a screw to the driver directly determines the overall production takt. Especially in high-throughput situations, shaving off just a few milliseconds per cycle yields a noticeable efficiency gain. This paper presents two collaboration-based improvements—one for long-distance feeding and one for s...
In automotive parts assembly, screws—being the key fasteners—must be counted with absolute accuracy; any deviation directly affects vehicle safety and build quality. Traditional magnetic‐pickup methods, once common on the line, are now showing clear drawbacks and can no longer meet modern production demands. The screw-counting dispenser was developed specifically to solv...
The tool used to calibrate an electric torque screwdriver is called a calibrator. Calibrators can generally be divided into two types: integrated calibrators and split-type calibrators.

In mechanical assembly and automotive repair, we often hear the old saying: "After tightening the bolt, turn it back half a turn." This may sound counterintuitive—why deliberately loosen it after going through the effort to tighten it? Is this just a piece of inherited "empirical folklore," or is there solid science behind it? To understand the rationale behind the "hal...
