Injection molding is a highly efficient manufacturing process, and the cold runner system plays a crucial role in ensuring consistent plastic part production. Unlike hot runners, cold runners rely on unheated channels to deliver molten plastic into the mold cavity.
This blog explores the step-by-step manufacturing process of cold runner systems in injection molds, covering design, machining, assembly, and troubleshooting.

In the mold manufacturing industry, protecting intellectual property (IP) and trade secrets is critical. A well-drafted Non-Disclosure Agreement (NDA) ensures that sensitive technical and business information remains confidential when shared with suppliers, manufacturers, or clients. Below are the essential clauses typically found in an NDA for the mold industry.

ABS (Acrylonitrile Butadiene Styrene) is one of the most widely used thermoplastics in injection molding, valued for its balanced mechanical properties, surface finish, and processability. This guide provides a comprehensive overview of ABS injection molding, covering material characteristics, supplier selection criteria, key processing parameters, and cost-saving strategies. We examine different ABS grades (general-purpose, high-impact, plating-grade, and flame-retardant), compare leading global and regional suppliers, and detail optimal temperature, pressure, and cooling settings. Practical solutions for common defects (silver streaks, sink marks, etc.) are presented, along with a step-by-step automotive dashboard case study. The article also explores emerging trends like bio-based ABS and smart process monitoring. 

Injection molding is a cost-effective manufacturing method for mass production, but the initial mold cost can be high. Many companies explore shared or second-hand molds to save money, but what if these options aren’t available?

Fortunately, there are still multiple ways to reduce injection mold costs through design optimization, material selection, manufacturing efficiency, and smart production management. Here’s a detailed guide.

Two-shot molding (also called dual-material or multi-component injection molding) is transforming medical device production by enabling seamless integration of multiple materials in a single manufacturing cycle. This advanced process delivers superior functionality, enhanced ergonomics, and cost efficiency for critical healthcare applications.
