One-Stop Mold Making Supplies for All Your Project Needs

Add Your Heading Text HereNeed mold making supplies for mass production parts? OYA is known as the best mold maker in China. With mold making facilities in house and resources from our partners, we are able to provide plastic injection molds for both rigid plastics and rubbers, metal injection molds for all types of precision stainless steel parts, and pressure die casting molds for aluminum, magnesium and zinc. We offer low-cost local production molds and high-quality exported molds for all your project needs.

Whatever you need prototype molds for the short-run production, or mass production molds for millions shots, OYA can handle them for you smoothly.

Our Advantages of Mold Making Services

OYA is an experienced provider of mold making services with lots to offer beyond our competitors:

1. 1. Fast DFM reports

We assess design feasibility during quoting and deliver a thorough DFM (Design for Manufacturability) report prior to production, addressing any potential manufacturing issues.

2. Wide range of molds

We offer several different types of molds, which means you can avoid splitting your projects; just send everything to us to ensure your project runs smoothly.

3. Fast Turnaround

Our large facility and machining capabilities allow us to build molds quickly, whatever the application or material, which means you can get your moldings completed faster.

4. Molding Capabilities

OYA can ship your molds to you directly, but we can also handle injection molding and other production services to deliver you prototypes and final parts using those molds.

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.

4. T1 sample

With the newly made molds, we make a T1 sample to have a clear vision of how the customer’s final molded parts will turn out.

2. Mold design and mold flow analysis

We employ predictive modeling software to simulate material behavior during mold filling, enabling design improvements.

5. Improvement if necessary

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

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.

6. Commence production and shipping

We manufacture the molds in accordance with the final specifications before shipping them to the customer.

Types of Molds We are Offering

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 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

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

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.

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

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

Mold Making Projects

OYA is a professional mold making company in China, offering a wide range of prototype molds & production molds for most types of production methods, such as plastic injection molding, metal injection molding, high pressure die casting, metal casting, profile extrusion and sheet metal. With our strong engineer and manufacture team, we have successfully produced 5K+ of molds and delivery 1 Million+ of parts to our customers.

Protect Glasses Mold

This is a 4 cavities mold we made for PU glasses injection molding. To protect people being infected during the critical time. We finish the mold within 10 days instead of 4 weeks. Find out how we speed up the mold making process.

Big Car Component Mold

One of our advantages is that we are able to make large size of molds from our CNC and EDM machines, and get the moldings done from our 1500 ton molding machines.

Reflector Mold Core

To get the best result of optical parts from injection molding process, it is important to achieve high gloss mold core from High Speed CNC Machining directly, instead of hand polishing.

Mold Making FAQ

What is mold making and when do you need it?

Molds are normally created to duplicate plastic and metal parts. After testing the prototypes and the market, it is the most cost-efficient way to launch your products at scale.

Should I choose a locally produced mold or an exported mold?

Generally speaking, making plastic or metal molds (and moldings) is cheaper in China than other countries. But shipping costs should also be considered: you will need to use air freight if you have a tight schedule; sea freight is much cheaper, but will usually take 40 days or more.

How long does a mold last?

A well-made, fully harden steel mold may be used for up to a million shots or injections, depending on the mold shape and injection material. Aluminum molds are less durable, which is good for short-run production with tight schedule.

Can molds be any shape?

Molding designs should avoid sharp corners, inconsistent wall thicknesses, and other features that restrict material flow.

When do I need full automatic mold?

Whatever you decide to use, in the end, what is the best cost-efficient way to get your parts done in the required quality is the key.
