What is Ceramic Injection Molding (CIM)?
Ceramic injection molding is like magic for making small, super strong ceramic parts. It’s a process that turns ceramic powder into detailed pieces for things like car engines, phone circuits, or medical tools. At Eshino Precision, we use CIM to make parts that are tough enough for the hardest jobs. But what exactly is CIM, and why is it so cool? Let’s find out!
How CIM Works
CIM starts with mixing ceramic powder, like alumina, with a special glue called a binder. This mix, called feedstock, is squished into a mold to make a part. Then, we take out the binder and heat the part super hot to make it hard and strong. This process lets us make really complicated shapes, like ceramic seals, that fit perfectly in machines.
Why CIM is Special
Unlike other ways to shape ceramics, CIM can make tiny parts with super tight measurements, often within half a percent of the perfect size. This is great for things like ceramic substrates in electronics. Plus, CIM can make thousands of parts quickly, which saves time and money. As Dr. Sarah Chen, a ceramics expert, says:
“Ceramic injection molding is a game-changer, offering unmatched precision for complex ceramic parts.”

Where CIM Shines
CIM is awesome for industries that need strong, precise parts. For example, it’s used in electronics for insulators or in cars for sensors. It’s also great for medical tools because ceramics don’t wear out easily. At Eshino Precision, we make CIM parts that last a long time in tough conditions.

Advantages of Ceramic Injection Molding
Ceramic injection molding is a top choice for making ceramic parts because it has so many benefits. It can create tricky shapes, be super precise, and save money when you need lots of parts. Let’s look at why CIM is so great for engineers and manufacturers at Eshino Precision.
Making Complicated Shapes
CIM can make parts with all sorts of cool details, like tiny holes or fancy curves. For example, ceramic nozzles can have special channels inside for spraying liquids perfectly. This is hard to do with other methods, but CIM makes it easy. That’s why it’s perfect for machine parts that need to be just right.
Super Accurate Parts
When you need parts to fit exactly, CIM is the way to go. It makes parts with smooth surfaces and super tight measurements, like ceramic substrates for electronics. This precision is super important for things like computer chips or car engines, where every piece has to be perfect.
Saving Money on Big Orders
Making the mold for CIM can cost a lot, sometimes $10,000 or more. But once the mold is ready, you can make thousands of parts, like ceramic valves, without spending much more. This makes ceramic injection molding really affordable if you need 500 or 10,000 parts. It’s a big win for companies making lots of stuff!
Less Extra Work
CIM parts come out almost ready to use, so you don’t need to do much extra shaping. This saves time and materials, especially for wear-resistant ceramics. It’s like getting a toy that’s already built—no extra assembly needed!
The Ceramic Injection Molding Process
Ceramic injection molding is like baking a super strong cake, but for ceramic parts! It takes a few special steps to turn powder into tough, precise pieces for things like car sensors or medical tools. At Eshino Precision, we follow these steps carefully to make sure every part is perfect. So, how does ceramic injection molding work? Let’s break it down!
Mixing the Ingredients
First, we mix ceramic powder, like zirconia, with a glue-like binder. This mix, called feedstock, is like dough for cookies—it needs to be just right. If it’s not mixed well, the parts could have flaws. We pick the best ceramics for the job, like alumina for electronics or silicon carbide for hot engines.
Shaping the Part
Next, we heat the feedstock and squish it into a mold using high pressure, up to 100 MPa. The mold is like a toy mold for Play-Doh, but super precise. This makes a “green part” that looks like the final piece but isn’t strong yet. For example, we use this step to shape ceramic valves for machines. The mold is made bigger because the part shrinks later.
Taking Out the Binder
Then, we remove the binder with heat, solvents, or special chemicals. This step, called debinding, is tricky because we have to be gentle to avoid cracks. Imagine slowly melting away the glue without breaking the part! Done right, it leaves a clean ceramic piece ready for the next step, like a ceramic bushing for tough jobs.
Making It Super Strong
Finally, we heat the part really hot—almost to its melting point—in a process called sintering. This makes the ceramic particles stick together, creating a super strong part. The part shrinks by about 15–20%, but we plan for that. The result? Tough pieces like ceramic seals that last a long time. Want to learn more about tough ceramics?

Materials Used in Ceramic Injection Molding
Ceramic injection molding uses different ceramics to make parts for all kinds of jobs. Each ceramic is like a superhero with its own powers, like being super hard or handling crazy heat. At Eshino Precision, we pick the best one for each project. Let’s look at the most popular ceramics we use in CIM!
Alumina: The Hard Hero
Alumina is super hard, with a hardness of 15–20 GPa, and it’s great at keeping electricity from flowing through it. This makes it perfect for alumina ceramic substrates in electronics or bushings in machines. It’s like a shield that protects parts from wear.
Zirconia: The Tough Champ
Zirconia is strong and doesn’t break easily, with a toughness of 5–10 MPa·m^0.5. It’s awesome for zirconia ceramic seals or medical tools, like dental implants, because it’s safe for the body. Check out our guide on zirconia benefits to learn more.
Silicon Carbide: The Heat Master
Silicon carbide can handle super hot temperatures and has a hardness of 25–30 GPa. It’s great for silicon carbide tubes in engines or furnaces. Its high thermal conductivity (100–150 W/mK) keeps things cool under pressure, as explained in our silicon carbide guide.
Silicon Nitride: The Shock Stopper
Silicon nitride is tough and resists sudden temperature changes, making it ideal for silicon nitride rods in car engines. It’s strong and reliable, perfect for automotive parts. Dr. Sarah Chen notes:
“The right ceramic in CIM can transform performance, from electronics to engines.”
| Material | Hardness (GPa) | Toughness (MPa·m^0.5) | Applications |
|---|---|---|---|
| Alumina | 15–20 | 3–4 | Substrates, bushings |
| Zirconia | 12–15 | 5–10 | Seals, implants |
| Silicon Carbide | 25–30 | 4–5 | Tubes, seals |
| Silicon Nitride | 14–18 | 6–8 | Rods, engine parts |
