(Ⅲ) How to deal with flow marks on injection-molded parts?
2024-09-27
Mold temperature too low Cause: The low mold temperature causes the molten plastic to cool too quickly in the runner, preventing full fusion. Solution: Increase the mold temperature to ensure the molten plastic flows smoothly and fuses completely. Injection speed too slow Cause: Slow injection speed causes the plastic to flow slowly, extending cooling time and forming weld lines. Solution: Increas...

The application of high-performance long glass fiber (LFT) materials in explosion-proof cameras
2024-10-28
As we all know, explosion-proof products have extremely specific requirements—explosion-proof ratings, material standards, sealing performance, functionality, certification requirements, and more. Among these, material requirements are particularly stringent. Taking explosion-proof cameras as an example, most currently use stainless steel or cast aluminum alloy for the casing, which can withstand ...

The application of advanced composite materials in drone structural components.
2024-10-28
Unmanned Aerial Vehicle (UAV), commonly referred to as "drone," is an aircraft that is operated without a human pilot on board, using radio remote control and onboard programmed control systems, or fully or intermittently autonomous operation via onboard computers. As a new type of aircraft, drones differ from manned aircraft in terms of operational requirements and mission objectives. Drones typi...

Overview of 8 Non-Destructive Testing (NDT) Methods for Composite Materials
2024-11-01
Composite materials are new materials created through advanced material preparation techniques that combine components with different properties in an optimized manner. In the 1940s, due to the needs of the aviation industry, fiberglass-reinforced plastics (commonly known as fiberglass) were developed, marking the beginning of the term "composite materials." After the 1950s, high-strength and high...

Eight Ways to Reduce Injection Molding Costs
2024-11-08
1. Production Workshop The layout of the production workshop should consider two main aspects: meeting production requirements and optimizing layout based on production flow, while ensuring flexible energy use under specific production conditions. (1) Power Supply: Ensure a stable power supply with a moderate buffer to avoid excessive energy waste from unused capacity. (2) Efficient Cooling Water ...
