Bridge tool – An injection mold that makes parts until the final tool is completed.  These molds or tools are not meant to be production tools.

We offer mold-making services at competitive rates and deliver in short lead times. All processes are performed under strict quality guidelines and the supervision of mold engineering experts.

Weld line - Also called a knit line, the juncture where two flow fronts meet and are unable to join together during the molding process. These lines usually occur around holes or obstructions and cause localized weak areas in the molded part.

Undercut – Can be a design flaw that results in an indentation or protrusion that inhibits the ejection of the part from the mold.  Other times undercuts are designed into a mold to ensure a part holds onto the correct side of the mold.

In overmolding, when the first layer of resin cools, a second layer of material is injected over it. We provide this service and can source all the requisite materials for you.

Polymer - A substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins.

Blow molding – The process follows the basic steps found in glass blowing. A parison (heated plastic mass, generally a tube) is inflated by air. The air pushes the plastic against the mold cavity to form the desired shape. Once cooled, the plastic is ejected.  This method is used to make plastic bottles.

FOW Mould is an injection mold supplier with decades of experience in mold design. Our molds are precise, durable, and designed to be efficient in the manufacturing process.

FOW Mould CNC machines are very precise and have high tolerances. This service is ideal for prototyping and producing actual parts made of metal, resins or a combination of the two.

Over molding – A two-shot process, in which two plastic substances, are injected into a mold sequentially, usually a harder base material with a coating of softer material.

Masterbatch – A solid or liquid additive for plastic used for coloring plastics or imparting other properties to plastics.

Alloy – A plastic alloy is a physical modification of an existing plastic to achieve higher performance and or functionality.  These alloys are often used in the automobile industry and to replace metal parts.

Flow marks - A wavy pattern or discoloration caused by a slow injection speed which allows the material to cool too quickly.

Our team of designers and injection molding engineering experts are highly-qualified and well-experienced in their craft. They keep up with evolving injection moulding industry trends and are continuously innovating new cutting-edge solutions.

Compression molding - The name of this molding method says everything.  A heated plastic material is placed in a heated mold and is then compressed into shape. The plastic can be in bulk but often comes in sheets. The heating process, called curing, insures the final part will maintain its integrity. This molding method is often used to make large objects such as automobile components.

Our injection molding factory is fitted with ultra modern equipment that churns out hundreds of injection molding parts on demand. We use premium quality materials for every project.

Additives – These compounds are added to resins to improve the overall performance and appearance of finished products.  A key trend in this area today is using additives that are made from organic materials such as eggshells, wood pulp, rice hulls or materials that improve the biodegradability of the plastic.

As a professional injection mold company in China, we provide services from plastic parts & mold design to mold making and molded parts manufacturing. We are capable of bringing injection molded product ideas into reality for a wide range of industries and applications.

Thermoplastic - A material that can be heated and cooled repeatedly without changing the material structure.  Highly recyclable.

Insert molding is suitable for assembling metal and plastic parts quickly and smoothly. We can design and manufacture all the components in-house and also insert-mold them for you.

Cold slug – A defect characterized by a small non-uniform area on the part caused by an improperly heated piece of plastic becoming attached to the part.

FOW only uses high-quality metal steel for injection molds and qualified resin for plastic parts. We are happy to provide composition analysis and other necessary test documents.

Core - A protrusion or set of matching protrusions, which form the inner surface of a plastic part. They are often considered they “male” side of the part.

We guarantee you a stress-free customer experience and complete discretion on all intellectual property. Look no further. Contact us today and let us get started on your project.

Thermoset – A material, which when heated, is pressed or molded into a shape.  The heating process changes the structure of these materials, and for this reason they cannot by re-heated.

Tie bars - Bars which provide structural support to the mold in the press.  The spacing between the tie bars dictates the size of the mold that can be placed into the injection machine. The mold opens and closes riding on the tie bars.

Colorant – A pigment system, usually in pelletized form, powder or liquid, which is mixed with resin to produce the desired color.

Multi-shot molding – A process where two or more plastic substances are injected into the mold to form a part.  Toothbrushes are often manufactured using this technique.
