Zinc Die Casting

Zinc die casting is a metal casting process where molten zinc (often a zamak alloy) is forced into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process

HAWIDO offers outstanding zinc die casting services for high-quality components at a great piece part price.  To achieve this, we are able to acquire raw zinc alloys at very low costs.  (We don’t focus on any single alloy, either – we are proud to provide die casting for every commercially available zinc alloy on the market.)  Due to this and our highly efficient manufacturing processes, we are able to offer a price per part that is 10 – 20% below our competitors.

For affordable zinc die casting services, we have focused on tooling prices, one of the larger costs involved in die casting.  We are proud to offer tooling at extremely low prices, generally 10% of the costs of our competitors.  Our low per-part costs and tooling costs make zinc die casting within reach of even the smallest manufacturers. 

Zinc die casting services from HAWIDO will provide you with an accurately cast and economical product every time to meet your specific needs.

Zinc Casting Advantages
Zinc alloys used in die casting development possess properties that make production simple, while providing an end-product that is durable. Zinc’s strength and hardness administer high impact strength and stability that make assembly uncomplicated. The high ductility of zinc alloys is ideal for the die casting process with a strong ability to be contorted and expanded without fracturing under pressure. Other strengths of zinc alloys used in die casting are:

• Low cost raw material for one of the most cost-effective processes and end products possible
• Strong stability allows a long-lasting end product with high quality finishing properties
• Thin walls assist in corrosion resistance for end products, increasing ability to outlast harsh environments
• Zinc is one of the easiest alloys to cast: it offers high ductility, high impact strength, and is easily plated
• It is economical for small die cast parts
• Zinc has a low melting point
• It promotes long die life

Additive Manufacturing

Additive manufacturing has gone through somewhat of a revolution over the last five to ten years. At one time thought to be a consumer-oriented technology, AM has now evolved into a viable industrial manufacturing solution.

As of 2019, the additive manufacturing industry is estimated to be worth over $9billion dollars. While this is still a fraction of the wider $12 trillion manufacturing industry, the landscape is evolving rapidly, creating massive opportunities for the industry as a whole.

As new players continue to enter the market and new technologies are developed, now is an exciting time to be a part of the change.

With these constant shifts in the market landscape, it can be difficult for manufacturers to keep track of the key companies offering solutions across the spectrum of AM.

HAWIDO bundles all it activities around additive manufacturing under one the top additive manufacturers in india. 3D post processing technology offers equipment, process technologies and consumables for the automated post processing and surface finishing of 3D printed components, be it for single piece manufacturing or volume production. The services also include consultation regarding the optimization of component designs for the actual printing operation but also for all post processing stages. HAWIDO– Manufacturing service partner offers a comprehensive service package that includes the design/engineering of new and re-design of existing products, the printing of metallic and plastic components as well as machining and surface finishing, all focused on the field of additive manufacturing. 

Design Engineers have always produced their designs based on achieving quality while utilizing the most economical methods of manufacturing. We’ve designed products to be produced by CNC machines, castings, injection molding, etc.

Additive Manufacturing (3D Printing) processes enable us to design with different boundaries and constraints. Design Engineers can incorporate geometric configurations for lightweighting, required strength, while eliminating time-consuming subtractive operations (such as EDM and CNC), conformal thermal dynamics, part-count reduction, and so much more.

CNC Machining

CNC machining is a metal fabrication method where written code controls the machinery in the manufacturing process. The abbreviation CNC stands for computer numerical control.

Contemporary CNC machines are fully automated, eliminating the need for a manual operator to directly control the CNC machine. The code determines everything from the movement of the cutting head and the part to spindle speed and RPMs. All they need is digital files with instructions about cutting trajectories and tooling.

The part’s shape and mechanical properties are defined in a CAD file. This information is then turned into manufacturing directives for CAM (computer aided manufacturing) software. Lastly, it is transformed into specific commands for a particular machine and loaded onto the CNC machine.

Although the majority of machining processes in the manufacturing industry are controlled by computers, then in a traditional sense CNC machining refers to only a few of these automated processes, namely milling, turning and drilling.

CNC machining is a subtractive manufacturing method. This means that material gets removed during the production process, making it the opposite of additive manufacturing, e.g. 3D printing.

The benefits of CNC machines include great positioning accuracy and high repeatability, so you get consistent results every time. CNC machining is suitable for both rapid prototyping and high-volume serial production.

Aluminum Extrusion

Extrusion is defined as the process of shaping material, such as aluminum, by forcing it to flow through a shaped opening in a die. Extruded material emerges as an elongated piece with the same profile as the die opening.

To aid in understanding the aluminum extrusion process think about a Play-Doh Fun Factory and how it works. Think of the Fun Factory as the extrusion press, the handle as the ram, the shape bar as the die, and the Play-Doh® as the aluminum billet. The first step is to choose the desired shape and color. Think of the shape as the die and the color as the temper and alloy needed. Next, the Play-Doh® is inserted into the holding chamber and pressure is applied to the handle, which forces Play-Doh® through the shape. In an extrusion press, pressure is applied to the billet by the ram where the dummy block is attached to the end of the ram stem. When Play-Doh® begins to emerge, it has effectively been “extruded”. The same principles apply to extrusions from aluminum billets but considerably more detailed and sophisticated technologies are involved.

Press size determines how large of an extrusion can be produced. Extrusion size is measured by its longest cross-sectional dimension, i.e. its fit within a circumscribing circle. A circumscribed circle is the smallest circle that will completely enclose the cross section of an extruded shape.

The most important factor to remember in the extrusion process is temperature. Temperature is most critical because it gives aluminum its desired characteristics such as hardness and finish.

In order to help us understand your needs and requirements and service you better, the following is a checklist of things to consider when submitting items to an extruder for quoting or new business:

1. Description or drawings of the part- talk to us early before the design is finalized.
2. Specifications to be met; Federal specs, military, ASTM, etc.
3. Alloy and temper; if unknown, indicate requirements for strength, corrosion resistance, machinability, finish, weldability, to aid the extruder in making a recommendation.
4. End use length and purchase length.
5. Tolerances; commercial, per drawing, other.
6. Surface Finish; mill, anodize, paint, exposed surfaces, etc.
7. Packaging; acceptable maximum and minimum weight per package and shipping and handling requirements.
8. Secondary fabrication requirements-mitering, punching, bending, anodizing, drilling, etc.
9. Product end-use.
10. Quantity needed; this order and on an annual basis.
11. Shipping date.
12. Special quality considerations.
