Application Methods of PTFE Powder Resin, 20 – 900 microns
1. Compression Molding Raw material: Suspension PTFE powder Process: Sieve powder → room-temperature cold pressing (10–50 MPa) → preform → sintering at 360–380 °C → slow cooling → machining Products: Sheets, rods, gaskets, sealing rings, valve seats 2. Paste Extrusion Raw material: Fine dispersed PTFE powder Process: Mix with extrusion aid (15–25%) → preform → plunger extrusion → de-oiling at 150–250 °C → sintering Products: Thin-walled tubes, wire insulation, thread seal tape 3. Isostatic Molding Process: Powder in flexible mold → pressureRead More …

Full-automatic Dip PVC Coatings Equipment For Dual-Color Adjustable Wrenches Spanners
DESIGN CONCEPT This full-automatic dip PVC coatings equipment for dual-color adjustable wrenches is engineered around the core demand for red-and-black finished tools, integrating efficiency, precision, and durability into its design. Tailored to the client’s requirement for dual-tone coating, it adopts a specialized three-oven configuration (one preheating oven + two curing ovens) to ensure consistent color definition across each wrench: the preheating step primes the metal surface, while separate curing ovens lock in the black and red PVC layers. Built withRead More …
PVC Dip Coating Plastisol: The Ultimate Solution for Durable, Versatile Surface Protection
Introduction to PVC Dip Coating Plastisol – Redefining Surface Performance PVC dip coating plastisol stands as a revolutionary material in the field of surface protection and enhancement, renowned for its exceptional versatility, durability, and adaptability across industries. A thermoplastic polymer composite, this specialized coating is formulated by suspending polyvinyl chloride (PVC) resin in a plasticizer, creating a viscous, liquid medium that transforms into a flexible, resilient film when cured. Unlike traditional coatings, PVC dip coating plastisol offers unmatched adhesion, impactRead More …
Why Sofubi & Vinyl Casting Toys Are Taking Over the Trendy Toy World

How To Eliminate Sagging And Air Bubble In PVC Dip Coating,Dip Moulding
Fluidity is a characteristic property of liquids. When a liquid adheres to a solid surface and flows along it, droplets form at the edges of the object. In industry, this droplet formation is referred to as the “sagging phenomenon” or “dripping point”. PVC plastisol liquid behaves exactly like this: when a workpiece is dipped into the plastisol and then lifted out, sagging occurs at the lower end of the workpiece. This sagging can sometimes affect the product’s appearance or even its functionalRead More …
How Melt Flow Index Affect LDPE Powder Coatings Performance
The melt flow index (MI), also known as the melt flow rate (MFR), is a key indicator to measure the melt fluidity of polyethylene LDPE powder coatings under specific temperature and pressure conditions. Its value directly affects the processing performance, film-forming quality, and final physical properties of the coating. The following are the specific impacts of the melt flow index on the properties of LDPE powder coatings: 1. Affect on Processing Performance Fluidity and Coating Efficiency The higher the meltRead More …
