Plastic Injection Mold

HON HAMN uses professional 2D, 3D and other software to design and to analysis plastic injection molds. The maximum mold size can match with 650-ton injection machine. During mold designing stage, experienced and talented engineers use the mold flow analysis program to study all possible situations of mold flow during injection. This will minimize the cycle time, stable the production quality, increase the lifetime of mold, and achieve the best efficiency. HON HAMN has end to end engineering solution for customer from product concept/design, to iterative prototyping and low volume production and to mass production.


HON HAMN continuously optimize and invest in the mold making capabilities and processing machines.

HON HAMN continuously update the latest software and provide special training for employees.

HON HAMN uses Coordinate Measuring Machine for precise dimension.

Mold Types

Production Mold in HON HAMN

HON HAMN uses imported brand steel such as NAK80, SKD11, P20 to build production injection molds for stable and high quality with over 300,000 ~ 800,000 plastic injection molding cycles upon request. HON HAMN offers LIFETIME MOLD WARRANTY if the molds stay and molding in our facility. All repairmen and maintenance cost are on us.

● Faster Production Time and Higher and Stable Quality Products.
● Less Wasted Material.
● Competitive Cost on Production Runs.

Export Mold

HON HAMN offers molds to be exported to the customer’s facility for production. All the molds are built to match customer’s specification, including type of steel, optimal runner system, gate type, cavities, and other features specified. Whenever the molds arrive at your facility, they could fit directly to your injection molding machines and ready for stable and high-quality production.

● High quality, competitive price and quick delivery.
● In-house mold trials and inspection before Worldwide shipping to your production facility.
● After-sale Technical and Maintenance support.

Insert Mold

HON HAMN can insert metal, plastic, or ceramic pieces into the molten plastic parts to offer multi-material products. Insert molding gives stronger joining forces between different material, less production cost and time compare to secondary processes with heat staking technology.

● Reduce part weight and dimension.
● Overall cost savings.
● Increase part strength and liability.

Family Mold

HON HAMN offers an economical way to produce a roughly equal size of the plastic parts, same material & color & quantity at the same time in a multiple-cavity mold. This is a great way to control assembled parts to have the same color.

● Less Molding and Production Cost.
● Easier Ordering and management in set.
● Uses MOLDEX-3D to have balanced mold flow.

Over-molding

HON HAMN provides over-molding process which one thermoplastic material is molded over another material to form one part. Two materials are strongly bonded together to form plastic component with unique visual appearance.

● Cost savings as no secondary operation or adhesive required.
● Increase productivity.
● Different texture and design for customer choice.

Protect Your Investment

Prevention Strategy

After a mold/die has run a set number of production cycles, inspections, maintenance and cleaning procedure must be performed. Different types of mold/die age with different speed, so scheduled maintenance needs to be executed and documented carefully. HON HAMN years of professional experience offers the ability to determine the best mold/die maintenance schedule specific to each plastic injection mold or metal stamping die.

Maintenance Schedule

Mold/Die repairs can be very costly, so it is extremely important to perform regular maintenance for plastic injection molds and metal stamping dies. This is the best way to protect your valuable investment and maintain consistent production of quality plastic/metal parts. With our advanced machine and professional experience, we provide quick and efficient mold/die repairs or revisions to ensure the production of high and stable quality components. Our insert type mold/die design also allow us to quick change of the damaged area instead of rebuilding the whole mold/die.

3D Printed Conformal Cooling Channel

Cooling Channel is a particularly important key for all types of plastic injection mold. With a well-designed cooling channel system, the heat of the mold can be controlled and provide less cycle time and better stable injected quality of the parts. In traditional, the cooling channels are in linear design and made by drilling straight holes in the core and cavity and they cannot provide an efficiency cooling effect when we have a complicated component design. Therefore, with the state-of-the-art 3D printing technology, we can build a conformal cooling design with metal 3D printing machine. Conformal cooling channels can follow the shape of the complex components and provide well cooling effect in all areas along the shape. With HON HAMN engineering teams, we use mold flow analysis software, MOLDEX 3D, to study the thermography and find out the heat spots that can be benefited from 3D printed conformal cooling channels with lower cost. With conformal cooling channel, we can be benefited for the following, better and stable injected quality, less warpage, less cycle time up to 65%, lower overall production cost, well balanced molding temperature and longer mold lifetime.
