The molding process of the 28mm injection molded cap
Raw material preparation and pre-treatment: Common materials: The 28mm injection molded cover is mainly made of PP (polypropylene) or PE (polyethylene). These materials offer good cost-effectiveness and comply with food contact standards. Drying treatment: If the moisture content of the material...Read more -
The application of injection mold inserts
The use of inserts is mainly to solve a series of problems in mold manufacturing, usage and maintenance, and its application scenarios are very extensive. 1. Facilitates processing and reduces manufacturing difficulty Deep cavity and narrow groove processing: Some very deep and very narrow ribs ...Read more -
POM automotive parts production process
POM (Polyoxymethylene) is known as “steel-like material” due to its high rigidity, wear resistance and self-lubrication properties, making it highly suitable for manufacturing automotive gears, bearings, fuel system components, etc. The production process of POM revolves around ̶...Read more -
Key points for injection molding of PF materials
In the field of engineering plastics, “PF” usually refers to phenolic resin (Phenolic resin), which is a thermosetting plastic and has specific requirements during injection molding. It is a completely different material from high-performance fluoropolymer PFA (perfluoroalkoxy resin)...Read more -
The injection molding process of marker pens
Phase One: Preparation Phase Product and Mold Design First of all, industrial designers will create 3D models of the pen barrel and cap, and determine their appearance, structure (such as pen clips, anti-roll structure, sealing clips), wall thickness, etc. Mold engineers will manufacture precisi...Read more -
Key points of injection molding for custom plastic parts
I. Part Design Stage: Laying the foundation for success This is the most crucial step. Good design is half the battle. Uniform wall thickness The wall thickness of the parts should be as uniform as possible. The reason is that uneven wall thickness can lead to different cooling rates, causing sh...Read more -
The maintenance process of injection molds
The maintenance of injection molds is a crucial link to ensure production stability, product quality and mold lifespan. A scientific and standardized maintenance process can significantly reduce downtime and production costs. The following is a detailed maintenance process for injection molds, w...Read more -
The production process of PET/PE blow molding bottles
The entire production process of blow-molded bottles (taking one-step injection stretch blow molding as an example) The core principle is to injection mold the parison and then immediately stretch and blow mold it on the same machine. This method is highly suitable for manufacturing high-perform...Read more -
Key points of injection mold forming
Phase One: Mold Design – The Blueprint for Success or Failure Design is the soul of a mold, determining its manufacturability, service life and product quality. DFM (Design and Manufacture Feasibility Analysis) Core: Communicate fully with product designers and review the 3D drawings of th...Read more -
Key points of ABS parts injection molding
Key Point One: Material Handling – “Drying is the lifeline” This is the most crucial first step. The slight hygroscopicity of ABS is sufficient to ruin the entire production batch. It must be thoroughly dried: ABS particles will absorb moisture from the air during storage and t...Read more -
The difference and application of PMMA material and PC material
PMMA (polymethyl methacrylate, commonly known as “acrylic”) and PC (polycarbonate) are two commonly used transparent plastics with significant differences in performance and applications. Below is a comparison: 1. Key Performance Comparison Features: PMMA Material Transparency: Extre...Read more -
PC lens hardening process
PC lenses (polycarbonate lenses) are widely used in the eyewear industry due to their advantages such as lightness and strong impact resistance. However, their surface hardness is low and they are easily scratched, so they need to be hardened to improve their wear resistance. The following is a ...Read more
