Mold Making

Mold Making Services

Almost 100 percent of our tooling is done in-house, using steel, aluminum and/or composite materials. We can create plastic injection molds, compression molds and centrifugal casting molds, among others.Our fully staffed tool and mold-making department is located at our plant in China. With design, engineering and manufacturing staff all under one roof, we provide turnkey solutions to meet your custom mold and molding needs.

Experienced Mold Makers

As an experienced custom manufacturing company, mold making at Elimold is one of our core strengths. We build high-quality molds with enhanced features to ensure strong performance over an extended lifespan. We have a dedicated mold making team that uses the most appropriate materials to build molds, demonstrating a very high level of craftsmanship. We have a foolproof method for designing and building all types of molds to ensure the highest level of part quality, no matter how high the production volume requirements.
Our mold designers convert simple sketches or 2D drawings into a 3D model of the mold to ensure an accurate build. We can also reverse engineer the part to be manufactured to obtain an exact representation. In addition to single- and multi-cavity molds for structural foam molding, resin transfer injection molding, and other process types, we also build multi-part molds to accommodate large objects. Using a wide selection of plastics, metal materials, and resins, we can create molds for prototype projects as well as production molds that meet various lifecycle requirements.
As a quality-conscious company, we perform dimensional checks to ensure accuracy, and all molds undergo any other types of necessary testing. We provide full technical support, perform repairs and rebuilds as needed, and record all maintenance activities as part of our tool history. With our production flexibility and focus on customer service, we can complete most molds in as little as one to two weeks, and we offer expedited service for time-sensitive projects. As a professional business, our team listens carefully to our customers and provides solutions that improve the quality of their products.

Types of Molds We are Offering

plastic injection mold 04 1

Plastic Injection Mold

Plastic injection molds are aluminum or steel molds used to make parts from a wide range of plastics, including nylons, acrylics, elastomers and reinforced materials like glass-filled polyamide. Custom plastic molds can last between 100,000 and 1,000,000 shots.
Metal Injection Molding service.png

Metal Injection Mold

Metal injection molding (MIM) is a form of injection molding where a metal and binder mix is used as feedstock. A metal injection mold is usually made from tool steel to withstand the metal injection, but we can also use aluminum.
die casting mold service

Die Casting Mold

Unlike many prototyping specialists, we can provide metal casting molds (and a low-volume casting service through our partners). These molds — typically made from hardened steel — can be used to make parts from aluminum, zinc, magnesium and other non-ferrous metals.
Investment Casting Mold

Investment Casting Mold

We can make low-cost investment casting molds by 3D printing a wax pattern and surrounding it with ceramic. The ceramic molds can then be used to make metal cast parts from metals like aluminum, zinc, magnesium, stainless steel and more.
elimold extrusion mould

Extrusion Mold

Our metal die molds can be used for aluminum extrusions of alloys like 6061 and 6063. We also make molds for plastic extrusions of materials like polystyrene, nylon, polypropylene and polythene.
Sheet Metal Mold

Sheet Metal Mold

Our experience making sheet metal molds for stamping and bending allows us to create sheet metal prototypes.

Mold Making Processes

Mold making is a complex process that requires a high level of skill and experience. Although each case is different, a typical order for a set of molds may go something like this:

1. DFM

As soon as the customer confirms the order of molds, we will start to do an initial analysis of the parts to get an idea of the part line, gate positions, etc.

2. Mold design and mold flow analysis

The second step involves using predictive modeling software, which allows us to see how the molten material will behave when it enters the mold, allowing for further improvements to the design.

3. CNC machining and EDM

We make the first molds using high-quality machining equipment, with the plastic, steel, aluminum, etc. chosen by the customer.

4. T1 sample

With the newly made molds, we make a T1 sample to clearly envision how the customer’s final molded parts will turn out.

5. Improvement if necessary

Based on our analysis of the T1 sample, we review the mold design and make any adjustments needed.

6. Commence production and shipping

We manufacture the molds by the final specifications before shipping them to the customer.

Mould Design Capability

High quality mold manufacturing is the core business of Elimold. We have 10 professional mold designers who have rich experience in material properties and mold structure, and have provided high-end customized mold manufacturing services for more than 10 years. They will take every case seriously. Before the design starts, our designers will run mold flow analysis and participate in technical meetings for each mold with the tool shop and various departments to avoid potential manufacturing problems and troubleshoot. All of these are a strong guarantee for our high quality and short delivery time.

Our design team will provide:

  • Industrial Design
  • Appearance Design
  • Structure Design
  • Mold Design (2D & 3D)
  • DFM (Design for Manufacturability)
  • Mold Flow Analysis

Mold Materials

Molds are an important tool for producing parts of various materials. Molds are used not only for large-scale production but also for small-scale trial runs because they are expensive to manufacture. Most molds are usually made of hardened steel, beryllium-hardened copper alloy, or aluminum. They can also be made using 3D printed plastics. The choice of the material used is based on its economics. Generally, steel is more expensive, but has a longer lifespan. Molds made from pre-hardened steel are less wear-resistant and are therefore used for smaller production runs and are best suited for larger parts. The hardness of pre-hardened steel ranges from 38 to 45 on the Rockwell C scale. Molds made from hardened steel need to be heat treated immediately after machining to make them more heat-resistant and wear-resistant, which helps to extend their service life.
Compared to steel molds, aluminum molds are less expensive, however, higher grades of aluminum such as QC-7 and QC-10 can be machined using modern computer equipment, making them capable of molding hundreds of thousands of parts. Aluminum molds are able to provide fast turnarounds and faster production cycles because they dissipate heat better. Depending on the application and production run, they can also be coated to make them more wear-resistant. If you want to analyze whether a mold is feasible before making a metal mold, you can reduce costs by using 3D printed plastic mold prototypes.

Why Do We Recommend Test Molding?

It’s just a little bit more costly but will lead to great improvements in your project. Test molds are mostly used in the phase when you need to test product functionality and material durability. Tooling and molding for manufacturing can be a big expense, but the cost will be even bigger if you have to remold due to design flaws and other problems. The test molding is exactly the process to help detect those flaws and make improvements to your product. Test molds are often used only a couple of times and cost less than 20% of a real mold for production. It’s a worthwhile investment.
