The sprue bushing is a vital component in plastic injection molds. It acts as the main channel through which molten plastic flows from the injection molding machine’s nozzle into the runner system of the mold. DefinitionA sprue bushing is a hardened steel, cylindrical insert located at the center

Functions of Mold SpringsMold springs are one of the most widely used elastic components in injection molds. Their main functions include:UnloadingMaterial PressingPushing MechanismsEjecting Molded PartsSprings are color-coded into five standard categories based on their load capacities, making i

In plastic injection molding, hot runner molds and cold runner molds refer to two different types of runner systems used to deliver molten plastic into the mold cavities. Here's a complete comparison to help you understand their differences, advantages, disadvantages, and application scenarios: 1.

In plastic injection molding, the gate is the entry point through which molten plastic flows into the mold cavity. The design and location of the gate significantly impact part quality, cycle time, and mold performance. Here are the main types of gates used in injection molding: 1. Edge Gate (Side

Selecting the right mold steel is critical for ensuring the quality, durability, and cost-effectiveness of plastic injection molds. Here are three basic principles to guide mold steel selection:1. Match Steel Properties to Product RequirementsThe steel's mechanical and physical properties must align

A DFM Report (Design for Manufacturability Report) is a technical evaluation document created during the early stages of a mold project. It assesses whether a part design is suitable for injection molding, and recommends changes that will improve manufacturability, reduce cost, and prevent productio

Moldflow Analysis is a computer-aided engineering (CAE) simulation tool used in plastic injection molding to predict how molten plastic will behave as it flows into and through a mold cavity.It’s part of a broader family of injection molding simulation software (like Autodesk Moldflow, Moldex3D, and

PET (Polyethylene Terephthalate) is a thermoplastic polymer from the polyester family. It's known for its strength, clarity, chemical resistance, and excellent recyclability. PET can be used in both amorphous (transparent) and semi-crystalline (opaque) forms, depending on how it's processed. Key P

TPU is a class of thermoplastic elastomers (TPEs), offering a unique balance of elasticity, transparency, and resistance to abrasion, oils, and chemicals.Types of TPU:Polyether-based TPU: Better hydrolysis resistance (good for water exposure)Polyester-based TPU: Higher mechanical strength and oil re

PVC is a versatile thermoplastic available in two main forms:Rigid PVC (uPVC): Hard, durable, and used in construction.Flexible PVC: Plasticized for flexibility, used in cables, hoses, etc.PVC is widely used because it’s:Flame-retardant (self-extinguishing)Resistant to water, chemicals, and corrosio
