What are the types of injection molding machines?
1. Vertical injection molding machine, as shown in the figure below, the axis of the injection molding device and the mold closing device of the vertical injection molding machine is in the same line, and perpendicular to the horizontal plane. The advantages of vertical injection molding machine covers an area
Double color injection molding application scene and application analysis
What are its specific application scenarios, and how to analyze the application materials? The application of double color injection molding 1) Used in night lights, mobile phone keyboards, car switches, etc., considering part of the requirements of light transmission. 2) It can be used on hand-held goods, such as pneumatic tool handles, insulated cups, etc., to increase tactile sensation; 3) Used in a variety of tonal appearance provisions of the commodity, such as …………
Where is the difference between liquid and solid silica gel?
One is solid. The non-solid silicone that flows like water we call liquid silicone; Of course, liquid silica gel has a certain viscosity, usually more dense than water, there fore, liquidity is not as strong as water. Liquid silica gel encounters curing agent or catalyst after curing reaction, according to different types of liquid silica gel will be cured into different hardness and different properties of solid silica gel.
Die acceptance standard
First, the appearance of the mold 1. The mold nameplate has complete contents, clear characters and neat arrangement. 2. The nameplate shall be fixed on the mold foot near the template and reference Angle. The nameplate is fixed and reliable and not easy to peel off. 3. The cooling water nozzle should be plastic block nozzle, if the customer has other requirements, according to the requirements.
Discussion on the difficulty of injection mold manufacturing
In order to produce qualified injection moulds, we must improve the quality of injection moulds, what measures can improve the quality of injection moulds processing? Cavity and core are vertical shape surface. Plastic parts of external and internal shape is formed directly by the cavity and core, these complex multiple-layered surface processing difficulty is bigger, especially within the blind groove cavity forming surface …………
Analysis of common defects of injection parts and improvement measures
A, lack of material 1. Reasons for defects: The small parts and corners of the finished products can not be fully formed, because the mold processing is not in place or the exhaust is not smooth, the molding due to the injection dose or pressure is not enough and other reasons, design defects (insufficient wall thickness). 2. Mold improvement measures: Revise the mold where the material is missing, take or improve the exhaust measure, increase the material thickness, improve the gate (increase the gate, increase the gate).
Detailed explanation of injection mold design steps
Composition of injection mold. It is mainly composed of forming parts (finger moving and fixed mold parts related to forming cavity parts), pouring system (the channel through which the molten plastic enters the mold cavity from the nozzle of the injection machine), guiding parts (to make the mold fit accurately), pushing mechanism (after the mold is divided, Plastic from cavity in the launch of the device), thermal control system (to meet the requirements of injection process for ……………
Basic principles of mold runner design
The basic principle of mold runner design is also called main runner, injection runner (Sprue) or vertical runner. It refers to the runner from the part where the nozzle of injection machine contacts the bushing of mold main runner to the end of the shunting channel.
Polishing of molding surface - injection molding technology for injection molding factory
The roughness of the molding surface directly affects the roughness of the surface of the plastic parts. Due to the increasingly widespread use of plastic parts, customers of plastic parts of the surface quality requirements continue to improve, ordinary mechanical processing and electrical
Detailed explanation of waterproofing design technology in product development
For a product, the customer does not require waterproof structure, but the user often uses it in the position with high density of water molecules. For example: bathroom, etc. So out of the responsibility for customer service, but also reflects the responsibility for precision mold products, but also for the health factors of consumers, precision mold ……
