Injection Molding Processes
CNC machining can work with a wide range of materials, including metals (such as aluminum, steel, titanium), plastics (such as ABS, acrylic, nylon), wood, foam, composites, and even certain types of ceramics. The suitability of a material for CNC machining depends on factors such as its hardness, machinability, and thermal properties.
Blow Molding
Blow molding involves clamping molten thermoplastic material into a mold and blowing air into it to expand against the mold cavity walls. After cooling and solidifying, the desired product shape is formed.
Compression Molding
Compression molding is mainly for molding thermosetting plastics and comes in two types: compression molding and transfer molding, which vary based on material characteristics and processing equipment.
Insert Molding
Insert molding refers to a molding process where a pre-prepared insert of a different material is placed into a mold, and then resin is injected. The molten material bonds and solidifies with the insert, resulting in a single integrated product.
Two Shot Molding
Two-shot injection molding injects two different-colored plastics into one mold, creating distinct color effects and enhancing the part's aesthetics with patterns.
Nano Injection Molding
It is a process that combines metal and plastic using nanotechnology. The metal surface is first treated with nanotechnology, and then plastic is directly injected and molded onto the metal surface, allowing the metal and plastic to be integrated.
Overmolding
Overmolding is when reinforcement materials are encapsulated within a matrix material, enhancing the composite's properties. It improves mechanical, thermal, and electromagnetic performance, with precise control for stability.
Injection Molding
Injection molding feeds granular or powdered raw material into an injection machine's hopper, where it's heated and melted. The molten material is then injected into the mold cavity through the nozzle and gating system, solidifying to form the desired shape.
Rotational Molding
Rotational molding involves adding plastic raw materials into a mold, which rotates along two perpendicular axes while being heated. This process allows the plastic to coat the entire mold surface evenly, forming the desired shape.
Structural Foam Molding
It is a manufacturing process that injects a gas into melted plastic resin to create lightweight, strong parts with a foamed core. It's used to produce large, thick-walled components with excellent strength and dimensional stability, commonly found in automotive and construction industries.
Extrusion Molding
Extrusion molding is mainly used for molding thermoplastic materials. It involves melting the material and pushing it through a shaped opening using a rotating screw. After shaping, the material is cooled and hardened to produce the final product.
Dip Molding
Dip molding uses the flowability of thermoplastic polymers under specific conditions, allowing them to be shaped into desired forms through jetting and solidification at room temperature using specialized tools and methods.
Thermoforming
Thermoforming, also known as vacuum forming, is a method where sheet materials are heated, vacuumed onto a mold, and cooled to create plastic products.
Injection Molding
Also known as injection-compression molding, utilizes the pressure of an injection molding machine to directly inject preheated rubber material from the barrel through a nozzle into the mold cavity, where it undergoes vulcanization to form the desired shape.
Compression Molding
Rubber compression molding places preprocessed rubber materials into an open mold cavity, which is then closed and subjected to pressure and heat in a vulcanizing press. This process causes the rubber to vulcanize and take shape.
Transfer Molding
Transfer molding, also called transfer compression or potting molding, places preprocessed rubber strips or blocks into a transfer mold cavity. The rubber is compressed by the transfer plunger and forced into the mold cavity through the gating system for vulcanization and shaping.
Extrusion Molding
Rubber extrusion molding heats and plasticizes rubber material in an extruder, pushing it forward with a screw or plunger. It then extrudes various semi-finished products using a rubber extrusion mold to complete the forming process.
Injection Molding Materials
