In the process of injection molding, dimensional deviations in plastic parts are a common issue. The size of plastic parts is typically influenced by factors such as the type of plastic material (including additives), the mold shrinkage index, and the injection molding conditions.

Gas marks are a common and troublesome issue in injection molding. They manifest as tree-like, wave-shaped scratches on the surface of plastic parts, centered around the gate, significantly affecting the product's aesthetics and quality.

Did you know that in the world of plastic mold processing, we sometimes encounter those annoying issues like sink marks? Don't worry, today we're going to dive into the reasons behind them and how to solve them!

This is a serious problem that urgently needs to be addressed. In recent years, although significant progress has been made in domestic plastic injection mold technology, there is still a certain gap compared to foreign manufacturing standards. Various factors can lead to mold cracking during operation.

The benefits of standardized processes in injection mold manufacturing are manifold. Firstly, it ensures that each set of molds adheres to the same quality standards, significantly enhancing product consistency. Secondly,

In the precise process of plastic injection molding, we often encounter a tricky problem – the gate becoming tightly adhered to the gate insert. Today, we will delve deeply into the causes of this phenomenon and explore effective solutions.

Brittle fracture is a common and challenging issue in the production of plastic products. So, what factors typically contribute to this phenomenon? Engineers from Yize Mould, with 15 years of rich experience in mould manufacturing, have summarized the following potential causes of brittle fracture:

A short shot refers to the phenomenon where plastic molds are incompletely filled due to insufficient plastic flow, resulting in incomplete plastic products. The main reason is improper injection pressure and speed (including excessive pressure loss caused by resistance). This is primarily influenced by the following aspects.

Water leakage in plastic injection molds typically arises from the following situations:

Segmentation Strategy Based on Product Characteristics: When designing mold cores for injection molding, the primary consideration is the complexity of product shape and function, which serves as the basis for reasonable segmentation to ensure ease of processing. To optimize the plastic injection molding process and enhance the feasibility of mold manufacturing techniques, we should aim to divide the mold into multiple components that are easy to grind, while also focusing on improving electri…

Burrs, as a frequent workpiece defect in Mould CNC machining, often appear after cutting operations. Especially during drilling or milling, these unwelcome guests tend to form on the bottom edges of parts, particularly for materials with good plasticity and low hardness.

In the field of mold processing, a noticeable issue when using CNC milling technology is the reduction of workpiece surface finish. This phenomenon is influenced by multiple factors, significantly impacting the final quality of mold processing parts.
