Our CEO Stephen Lang started his career selling plastic injection molding 30 years ago and we continue to source the best mold factories in the world.
Injection molding is one of the most widely used processes for creating plastic parts. It’s also Marche Internationals flagship service. The process starts with creating a metal mold of an intended part. Molten plastic material is then injected into the mold and allowed to cool and solidify. This requires the mold to have an integrated tooling system for improved cycle times. For large and multi-cavity tools, hot runner systems are used to keep the plastic in a molten state until filling the entire cavity. Marche is able to create quality molds due to our superior understanding of molding intricacies.
Our network of tooling factories are able to produce quality plastic injection molding that is designed to meet all client specifications. In addition to traditional molding features, we have expertise with:
- Hot Runner Systems
- IML (In-Mold Labeling)
- IMD (In-Mold Decorating)
- Over Molding – 1 or 2 shot tools to apply a rubber or soft plastic finish to a part
- Insert Molding – Threaded inserts, weights, or other custom designed parts
Typical Tooling Steels that we are capable of implementing through Hardened Tool Steels:
- 420 SS
Pre-Hardened Tool Steels
Our Network of tooling factories has the ability to machine, EDM and texture the mold using the chosen tooling steel. For hardened tool steels, the tool cavity will be heat treated to the requested hardness, based on the client production requirements.
More than Plastic Injection Molding
Die cutting is a process in which parts are cut out of sheet material. The material can be anything from cardboard to sheets of EVA foam. The resulting cut-outs are used for a variety of simple parts.
Blow molding is a process used to create hollow, thin-walled parts. This process is typically used in packaging, toys, and bottles. Blow molding begins with a tube of soft plastic that is extruded into the mold cavity. Then, a “blow-pin” is used to inflate the tube and push the tube of plastic against the mold wall creating the desired shape. Usually there is scrap plastic on the parting line that needs to be trimmed from the part. The trimming process can add labor cost. Blow molding is less expensive than plastic injection molding because molds can be made from aluminum instead of stainless steel.
The types of materials that are commonly used in blow molding are thermoplastics and PE (polyethylene). PE is most common and is found in items such as milk jugs and laundry detergent bottles. Clear plastic materials may also be used. These would include materials like Polyester or PET. PET is commonly used in drink bottles.
Stamping parts can be produced with a variety of different methods, but typically requires multiple cutouts and bends to create a finished part. Marche International provides solutions for creating sheet metal shapes that expand on the capabilities of standard breaks and presses.
Drawing is the process of creating a part by using a punch to push the sheet metal into a form known as a die. The metal is stretched to fit the concave form which can range from several inches to over a foot deep. These tools can be created for steel and aluminum.
The key factor in providing competitive pricing for our clients is our vast network of tooling manufacturers in China. It’s not uncommon for us to get quotes from 10 or more molding factories for one project.
