Analysis shows that filter media made by electroforming deliver a markedly narrower particle size distribution. Compared with woven wire mesh filters, they require less frequent cleaning and maintenance, allow extended filtration cycles and service life, and greatly boost production efficiency.The rigid structure of electroformed sieves ensures apertures never deform. Aperture sizes can be controlled within extremely tight tolerances, with minimal dimensional variation across all holes on the entire surface. Unlike woven wire sieves, electroformed mesh features a flat, smooth surface.In addition, woven sieves are only available with fixed standard aperture sizes. Electroforming technology, however, can produce square, round or custom geometric apertures in 1-micron increments across the full range of 3 μm to 2000 μm.The weaving process used for woven test sieves creates inherent fluctuations in nominal aperture dimensions within a single mesh cloth. For instance, a woven test sieve labeled 63 μm typically has actual apertures ranging from 56 μm to 69 μm while still meeting industry specifications.By contrast, an electroformed sieve also marked 63 μm maintains apertures between 61 μm and 65 μm; ultra-precision electroformed sieves achieve an even tighter range of 62 μm to 64 μm.

When the material has fine particle size, high mud content and small screening size, moisture plays a decisive role in causing mesh blockage.If the material moisture content exceeds 5% and drying treatment is unavailable, targeted selection of sieve surface and mesh aperture shall be carried out.When the moisture content is higher than 8%, wet screening shall be adopted.For materials containing a large amount of flaky particles, it is necessary to adjust the material crushing method and the particle size matching of different crushing processes.Proper adjustment of mesh tension is an effective way to reduce mesh clogging. Appropriate tension enables the sieve mesh to generate slight secondary vibration together with the supporting beams, so as to effectively alleviate blockage. The specific operation is to equip tension hooks with constant tension structures, i.e. install springs on tension bolts.

There are two common types of laboratory testing instruments: test sieves and tap sieve shakers. They share some similarities but also have obvious differences. Below is a detailed introduction to their distinctions.Classification of Testing EquipmentThe tap sieve shaker is a complete machine, while test sieves are accessories matched with the machine. The tap sieve shaker is the main equipment, and test sieves belong to measuring tools.Tap sieve shakers are made of cast iron, whereas test sieves are manufactured from stainless steel.Tap sieve shakers require electric power to operate; test sieves can be used either on a machine or manually.Tap sieve shakers must work with matched test sieves; test sieves can be operated by hand or installed on a tap sieve shaker.Introduction to Test Sieves and Tap Sieve ShakersTest sieves are generally round and available in numerous sizes. Mesh count is commonly used to mark specifications, though the accurate labeling standard is "aperture size / wire diameter".The tap sieve shaker (also called tapping standard sieve shaker or tapping vibrating sieve) is one of the widely used laboratory testing instruments, specially designed for particle size analysis with test sieves. Its structure mainly consists of a machine base, test sieve sets and a transmission mechanism. It is applicable to particle composition inspection of ordinary abrasives, grading and particle size testing of superhard materials.

Wire Thread Insert, abbreviated as thread insert, is a new type of internal thread fastener. It is wound from high-strength, high-precision, corrosion-resistant steel wire with a diamond-shaped cross-section and smooth surface. It looks like a spring and features an installation tang at one end. Using special tools, the insert is screwed into a pre-machined threaded hole via the tang. The outer surface of the insert clings tightly to the hole wall by elastic force, while its inner surface forms a brand-new standard thread for screws and bolts. This prevents direct contact between fasteners and the base material, protecting both the substrate and screws. When applied to low-strength base materials such as aluminum and magnesium alloys, it significantly boosts thread tensile strength and wear resistance. It also optimizes thread stress distribution to share load evenly across the whole thread, improving the overall connection strength. Besides, it can repair worn or damaged internal threaded holes.FeaturesWire thread inserts are precision concentric assemblies of internal and external threads. Their outer diameter in the free state is slightly larger than the mounting thread diameter. After installation, they lock firmly inside the threaded hole to form high-precision internal threads that meet international standards, outperforming directly tapped threads in all performance indicators.The insert creates a spring-loaded connection between the screw and mounting hole, eliminating pitch and thread profile errors between internal and external threads. Load is evenly distributed on every thread turn with vibration damping performance, reinforcing the internal thread and raising the load capacity and fatigue resistance of threaded joints.Made of high-strength, smooth steel wire, the insert reduces friction and abrasion with screws, cutting friction torque on fasteners by up to 90%. Maximum preload and screw tension can be achieved with minimal tightening torque to guard against screw loosening. Meanwhile, under the same strength requirement as ordinary internal threads, inserts greatly enhance threaded hole strength, saving material and reducing component weight and size.When threads are machined incorrectly or internal threads get damaged, the conventional solution is to enlarge threads and matching screws. Using wire thread inserts for restoration quickly restores threads to their original dimensions without increasing weight or volume, salvaging key equipment components. In addition, repairing equipment with scarce imperial threaded holes is troublesome; wire thread inserts enable fast conversion between imperial and metric thread standards.Manufactured from heat-resistant and corrosion-resistant premium steel, wire thread inserts avoid common thread failures such as seizure, galling and rust lock-up in threaded connections.
