(Ⅱ) How to deal with floating fibers on injection-molded parts?
2024-09-27
Mold temperature too low Cause: If the mold temperature is too low, the melt cools too quickly during flow, causing the glass fibers to not be fully encapsulated by the base resin and float to the surface. Solution: Increase the mold temperature appropriately to ensure the melt has sufficient fluidity to uniformly coat the glass fibers. Regularly check the mold temperature control system to ensure...

(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 six essential requirements for precision injection molding
2024-10-25
In injection molding design, in addition to general mold design considerations, the following aspects should be given special attention: 1. To achieve the desired product dimensional tolerance, appropriate mold dimensional tolerances must be considered. 2. Preventing fluctuations in molding shrinkage rates should be accounted for. 3. Preventing molding deformation must be addressed. 4. Avoiding de...

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 ...

Long Carbon Fiber vs. Short Carbon Fiber in 3D Printing
2024-11-11
In 3D printing, both long carbon fiber and short carbon fiber are used as reinforcement materials to enhance the strength and durability of printed parts. Here’s an overview of their differences: 1. Long Carbon Fiber Long carbon fibers are continuous strands that are incorporated into the printing material. This type of fiber provides superior strength, stiffness, and structural integrity to the p...

How to increase the gloss of ABS injection-molded products?
2024-11-11
Injection Mold 1. If the mold cavity is poorly machined, with defects such as scratches, micro-pores, wear, or rough surfaces, it will affect the gloss of the plastic part. To address this, ensure precise machining of the mold to achieve a lower surface roughness for the cavity; if necessary, polish and chrome-plate the cavity. 2. If the cavity surface has oil stains, watermarks, or excessive mold...
