Mold making is the process used to duplicate three dimensional models or objects. A model is any object that has depth and an original model can be made from almost anything. If you were making your own object to mold you might use clay rock or plastic. Through the use of a mold making material a negative or a reverse of a model part is made the negative can then be used to cast a second part that is the same size and shape as the original part.
Injection moulding is a manufacturing process that allows for parts to be produced in large volumes. It works by injecting molten materials into a mould (or ‘mold’ in the United States). It is typically used as a mass production process to manufacture thousands of identical items. Injection moulding materials include metals glasses elastomers and confections although it is most commonly used with thermoplastic and thermosetting polymers.

First of all we need to receive your 3D drawings (stp step igs iges format) and quote according to your needs such as quantity material surface finish etc.
Before the mold is assembled to the injection molding machine the drawing needs to be programmed so that we can clearly see the process of the material as it enters the mold for further adjustments and modifications.
After the metal or plastic injection molding is determined it is put into production. After confirming the molding model with the customer the precision inspection and surface treatment are carried out.
After the mold is complete it is assembled into the injection molding machine. During the injection process we check that the machine is functioning properly (or not) make some necessary tool adjustments and generate a new sample.
After the samples are surface treated as specified by the customer they will be checked again for dimensions.
According to customer requirements choose the surface treatment method. At the same time quality inspection work is carried out.
The last step is to check whether the mold needs to be adjusted according to the analysis of the sample and whether the test sample meets the previous requirements.
After the samples have been tested to meet the preliminary requirements the samples can be packaged and shipped.
Injection molding is two large metal mold halves coming together a plastic or rubber material is injected into the cavity they form. Even though the plastic materials being injected are melted they aren’t really heated; the material is pressed into the injection ports (called gates) via a large auger screw. As the material is compressed it heats and begins to flow into the molds. Once it cools the two halves separate again and the part pops out. Repeat ten thousand times and you have a run of injection molded parts ready for use.
A wide variety of industries benefit from the highly versatile process of injection molding including: Medical & Pharmaceutical Eletronics Construction Food & Beverage Automotive Toys Agriculture Consumer Goods Sporting Goods
Injection molding is a fast cost effective and highly precise manufacturing process used for mass producing complex molded parts in a variety of materials including thermoplastics polymers aluminum and glass.
There are several types of injection molding processes including: Custom plastic injection molding Overmolding Insert molding Cube molding Die casting Gas-assisted injection molding Liquid silicone rubber injection molding metal injection molding Micro injection molding Reaction injection molding
How long an injection mold can last depends on several factors: mold material number of cycles operating conditions and time between production runs. The life expectancy of an injection mold can range from 1M+ cycles to less than 500 cycles based on the above criteria.
Although quite similar the difference between forming and molding comes down to their unique features and benefits depending on the application they are being used for. Injection molding is more suitable for large production runs of small intricate parts and involves injecting liquid polymers into a mold using extreme pressure and temperatures. Thermoforming also referred to as vacuum forming is more suitable for shorter production runs of large-scale designs and involves forming heated plastic sheets to a mold's surface.
ABS is a low-cost engineering plastic widely used for pre-injection molding prototypes.

Electropolishing is an electrochemical process used to clean metallic surfaces and reduce micro-roughness of stainless steel parts. Useful to remove a thin (up to 10μm) layer of material and improve surface finish.
Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish. Not advisable for applications where corrosion resistance is required.
Applicable on steels black oxide is a Conversion coating used to improve corrosion resistance and minimize light reflection.
Bead blasting adds a uniform matte or satin surface finish on a machined part removing the tool marks. This is used mainly for visual purposes and comes in several different grits which indicate the size of the bombarding pellets. Our standard grit is #120.
Parts are brushed and then anodized type II. Ideal for increasing the corrosion resistance of the part. Typically results in a glossy color.
Powder coating is a strong wear-resistant finish that is compatible with all metal materials.
The anodizing type III coating is applied directly to a surface as machined (no other mechanical finish applied). Type III anodizing provides excellent corrosion and wear resistance suitable for functional applications.
Parts are anodized (type II) directly after machining. The most cost-effective anodizing option. Ideal for non-cosmetic functional parts. Used to improve wear and corrosion resistance.
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations).
