Professional Threaded Cap Injection Molds: Comprehensive Analysis of Materials, Lead Time and Precision Manufacturing

Product Introduction

Threaded cap injection molds are the cornerstone of the packaging industry, widely used in the beverage, food, cosmetics, and pharmaceutical sectors. A high-quality mold is crucial for producing caps with excellent sealing performance, durability, and user-friendly experience. From a professional perspective, this article details the standard production lead time and core manufacturing requirements of threaded cap molds, and provides an in-depth analysis of five commonly used plastic materials for caps, helping you make the most informed decision for your next project.

Mold Lead Time and Core Manufacturing Requirements

We adopt a standardized production process to ensure quality and efficiency:

• Standard Lead Time: 18-25 working days, covering the entire process of design, processing, assembly, mold testing, and sample confirmation.

• Rush Lead Time: 12-15 working days, providing a quick response solution for urgent projects.

To ensure mold performance, we adhere to strict manufacturing specifications:

1. Precision Thread Design: CNC (Computer Numerical Control) and EDM (Electrical Discharge Machining) are used to ensure the thread tolerance is within ±0.03mm. Meanwhile, mold flow analysis is applied to optimize gating and prevent shrinkage.

2. Efficient Demolding System: Sliders or thread-unscrewing mechanisms are adopted to achieve smooth demolding, protect threads from damage, and ensure the mold life exceeds 1 million cycles.

3. Material and Cooling: Core components are made of high-quality mold steel such as S136 or NAK80; the cooling water channels are optimized to achieve rapid cycling and stable production.
