The Role and Working Principle of Lifters in Molds

1. Definition of a Lifter

A lifter is a common ejection mechanism in injection molds, primarily used to address demolding challenges caused by undercuts in plastic parts. It operates through an angled movement (typically driven by an angle pin or guide rail) during mold opening, allowing the part to be released smoothly without sticking or damage.

2. Functions of Lifters

(1) Resolving Undercut Demolding Issues

-When a plastic part has internal recesses, side holes, or snap-fit features, standard ejector pins cannot release it directly. Lifters provide lateral movement to clear the undercut, enabling successful ejection.

(2) Simplifying Mold Structure and Reducing Costs

Compared to sliders or hydraulic core pulls, lifters have a simpler design, making them cost-effective for small to moderately complex undercuts.

(3) Improving Production Efficiency

Lifter movement is automatically controlled by mold opening/closing, eliminating the need for external power sources (e.g., hydraulics or pneumatics), making them ideal for high-speed injection molding.

(4) Enhancing Product Aesthetics

- Lifters are usually placed on non-cosmetic surfaces (e.g., inner sides or bottoms) to avoid visible parting lines or ejection marks.

3. Working Principle of Lifters

Lifter movement relies on mold opening, following this typical process:

1. Mold Closing

- The lifter remains stationary during injection to ensure proper part formation.

2. Mold Opening

- As the mold opens, the lifter is pushed by the ejector plate while being guided by an angle pin or rail, forcing it to move at an angle.

3. Ejection Completion

- The lifter slides at a predetermined angle (usually 5°–25°) to clear the undercut, followed by full part ejection via ejector pins.

Schematic:

Mold closed → Mold opens → Lifter moves along angle pin → Clears undercut → Part ejected

4. Common Types of Lifters

(1) Standard Lifter

- Driven by an angle pin, suitable for simple undercuts.

(2) Delayed Lifter

- Remains stationary initially, then moves at an angle later, ideal for complex undercuts or multi-stage ejection.

(3) Hydraulic Lifter

- Powered by a hydraulic cylinder, used for long strokes or high-precision applications (less common, often replaced by sliders).

(4) Two-Stage Lifter

- Uses dual motion (lateral shift followed by ejection) for deep cavities or special geometries.

---

5. Key Design Considerations for Lifters

(1) Angle Selection

- The lifter angle (typically 5°–25°) must balance ease of ejection with wear resistance. Too shallow an angle may cause sticking; too steep may lead to jamming.

(2) Material and Heat Treatment

- Lifters are often made of hardened steel (e.g., SKD61, H13) and heat-treated (HRC 48–52) for durability.

(3) Lubrication and Guidance

- Wear plates or oil grooves reduce friction and extend lifter lifespan.

(4) Stroke Calculation

- The ejection stroke must exceed the undercut depth to ensure complete release.

6. Conclusion

Lifters are essential in mold design, particularly for plastic parts with undercuts. Their simplicity, cost efficiency, and reliability make them widely used in electronics, appliances, automotive components, and more. Proper design of angles, materials, and motion ensures longer mold life and higher product quality.

Precision injection molding characteristics

The Precision injection molding is generally referred to as the precision of forming parts and surface quality is demanding high technology, some people think that precision injection is the size of plastic parts to achieve the accuracy of 0.01 ~ 0.001 mm injection molding process. In recent years, with the electronic, medical, communications, automotive, and other industries. With the rapid development of people’s plastic products, high precision, high-performance requirements. The traditional plastic molding process has been difficult to meet the current high standards. Is one of the most important plastics molding methods. Therefore, precision injection molding technology more and more people’s attention. Making precision injection molding technology continues to progress, new technology continues to emerge. Factors that affect precision injection molding require high dimensional accuracy, low warpage, excellent transfer characteristics, and excellent optical properties.

Therefore, it is on the injection molding machine, injection mold, molding process, raw material properties. And formulations have special requirements, affecting the many factors of precision injection molding. According to the current actual production point of view, the impact of precision injection molding factors are the following aspects:

Plastic shrinkage design of precision plastic products, plastic shrinkage should be considered.
The shape and size of the product The shape and size of the plastic parts have a great impact on the accuracy of the parts, the production practice shows that the more complex the shape of the product and the larger the size, the lower the accuracy
Mold structure The accuracy of plastic parts and mold cavity number and production volume are closely related. It is also shown that the accuracy of the single-cavity mold structure is higher than that of the multi-cavity mold, and the accuracy of small-mass production is higher than that of large quantities.

The false Chinese injection mold companies on the Internet

When you are trying to find a Chinese injection mold companies on the Internet, after you search for ” Injection mold China in GOOGLE”, “injection molding company China” and so on, Google gives you the result is ” some companies tell you he comes from the United States, then there are many associates and partners in China, some companies will tell you, I am a Chinese injection molding company, we can do everything that you want to, he can provide.

As a Chinese mold owner with a conscience. I can definitely tell you that you find only a trading company, a trader, or a Liberal profession. Never blame Google. Google only gives you information, but he doesn’t have the ability to tell you the truth. These false deals are to make a difference between you and the Chinese injection molding company. In order to maximize profits, they will desperately lower domestic production factory prices. They will find some China small mold factory, with simple equipment and rough processing mode to lower the price. The accuracy and quality of your products are not guaranteed, perhaps you will tell me I really visit the factory. It’s a big company, the equipment, and the staff is very good, I check the injection mold quality there by myself.

I have to tell you, how do you know the whole mold and injection molding processing is done in this factory? Do you believe you can get $10 for a $1 product?

The real mold manufacturing plant

As an export mold and injection molded parts with 20 years of history, the real mold manufacturing plant, I would like to share a little experience with you.

1.Don’t believe that a Chinese injection mold company will have representative offices abroad.

2.No Chinese company will have an Associates with a foreign company. It’s just another customer form.

3.Each company is specialized in some types of injection molds and plastic molding products. Which will be nothing, this is not professional.

4.These fake companies are Internet marketing experts. You can easily find them on the GOOGLE home page.

5.The cheapest is not necessarily the real producer. There are many small factories for 1-5 people in China. Their prices are so cheap that you can’t imagine them. Of course, their quality is also cheap to your imagination.

Overmolding Insert molding in China

Plastic molding process:

The overmolding is one of China's plastic molding processing methods. With plastic material or parison as raw material. make its external force by heating and a method of the shape of the products needed.

Overmolding is the piece, pipe, plate, such as plastic material, heating in a kind of rubber state, deformation by an external force. And moulding for all kinds of simple shapes. Then through cooling stereotypes and products. Over-molding including the hollow blow molding. Thermoforming, stretching film-forming method. such as only applies to thermoplastic plastic molding. Chinese over-molding is in molding on the basis of a method.

Mainly includes the following several forming methods:

Thermoforming

Hot forming is a thermoplastic plastic sheet that is heated to softening, the gas pressure, liquid pressure. Or mechanical pressure, using the appropriate tooling. Or jig and make its products a molding method. The plastic thermoforming method is many, generally can be divided into:

Injection Molding using a single-mode (male die and female die) or to Die. Using plus mechanical pressure or weight, to make all kinds of products from the sheet forming method. It is different from processing molding. This method is suitable for all thermoplastics.

Differential pressure molding using single-mode (male Die and female Die) or to Die. Also don't have to Die. In the gas under the action of pressure difference. Make the heating to soft plastic sheets with mould surface. Cooling is made after forming methods of various kinds of products. It can be divided into vacuum forming and differential pressure molding.

Thermoforming is especially suitable for thin walls, the large surface area of the manufacturing of the product. The commonly used plastic varieties have various types of polystyrene, organic glass, PVC, ABS, polyethylene, polypropylene, polyamide, polycarbonate, polyethylene terephthalate, etc.

Thermoforming equipment including clamping system, heating system, vacuum. And compressed air system and forming mould, etc.

Biaxial tensile

To make molecular reorientation of thermoplastic film or plate, etc. Especially above the glass transition temperature of the bidirectional tensile process. Stretch orientation between the glass transition temperature and the melting point of the polymer. After directional tensile and rapid cooling to room temperature, the film or monofilament. The drawing direction has a lot to improve mechanical properties.

Suitable for directional stretching of the polymer is polyvinyl chloride (PVC), polyethylene terephthalate. Polyvinylidene chloride, poly (methyl methacrylate, polyethylene, polypropylene, polystyrene, and some of the styrene copolymer.

Overmolding Insert molding in China: Insert Molding

Insert Molding is a thermoplastic material or stock under pressure for products with mold the molding method. In the plastic molding process of molten (softening) under temperature (below the melting point at least 10-20 ℃). Solid-phase forming. Including plastic of non-crystalline class above the glass transition temperature. A melting point below the high elastic area processing is often called thermoforming. And below the glass transition temperature is called cold forming or room temperature molding processing. Also often called cold working methods or room temperature plasticity of plastic processing.

The method has the following advantages: a short production cycle. Improve the toughness and strength of products. Simple equipment can produce large and super large products. Cost reduction. The defect is: hard to produce complex shapes. The precision of products. It is difficult to control the production process. The products are easy to be out of shape, craze.

Solid-phase forming includes sheet roll, deep drawing or sheet stamping, hydraulic forming, extrusion, cold stamping, roll forming, etc.
