The cap of a
plastic container appears simple due to its small size, but in reality, it is a precision part that requires detailed consideration of sealing force, opening and closing feel, assembly accuracy, and durability.
In particular, products that are opened and closed repeatedly, such as one-touch caps or screw caps, may have significant differences in completeness depending on the design level of the mold and injection molding conditions.
Today, we will introduce in detail the main products and technologies of , a Taeyoung company that has been focusing on the field of cap molds since 1992, and the injection molding equipment , which supports stable product production.
What kind of company is Taeyoung Corporation?
Taeyoung Corporation is a precision cap mold manufacturer located in Bucheon-si, Gyeonggi-do.
Since its establishment in 1992, we have continuously designed and manufactured various plastic cap molds such as one-touch caps, screw caps, oil caps, toothpaste caps, and wide-mouth caps.
Based on the design technology and manufacturing experience accumulated while focusing on the cap mold field for a long time, we currently have experience in producing more than 500 types of cap designs.
TAEYOUNG CAP MOLD is characterized by not only manufacturing molds, but also operating its own production system that includes product design, mold processing, test injection, product production, assembly, and quality control.

was selected as a root company in 2025, once again being recognized for its long-accumulated manufacturing technology and production base.
What are the main cap molds produced by Taeyoung Corporation?
Taeyoung Engineering Co., Ltd. designs and manufactures a variety of cap mold products according to purpose and shape.
Representative products include the following. What kind of product is the
one-touch cap mold?
one-touch cap is a cap with a hinge structure that allows it to be easily opened and closed with one hand.
It is used in a variety of fields such as shampoo, detergent, cosmetics, and food sauce containers, and requires precise design to ensure a smooth fit between the lid and body.
Taeyoung Corporation manufactures not only general one-touch caps but also one-touch cap molds with automatic assembly equipment.What kind of product is the
screw cap mold?
screw cap is a screw-type cap manufactured so that the thread of the container mouth and the internal structure of the cap are engaged.
Widely used in mineral water bottles, beverage bottles, medicine containers, and household goods containers.
Because fastening force and sealing force are important for screw caps, the thread size, thickness, and injection shrinkage rate must be precisely calculated. What kind of product is the
oil cap mold?
oil cap is a cap used on automobile engine oil or industrial lubricant containers.
High airtightness and durability are required to prevent contents from leaking during transportation and storage.
Taeyoung Corporation is producing cap molds tailored to the usage environment and container specifications based on its experience in producing lubricant caps. What are the characteristics of the
cosmetic/pharmaceutical cap?
Appearance quality, hygiene and ease of use are important for caps in the cosmetics and pharmaceutical sectors.
Even small surface scratches or injection marks can affect the product image, requiring mold surface processing and injection condition management.
Taeyoung Corporation has experience in manufacturing various types of products, including toothpaste caps, pointed caps, and caps for various cosmetic containers.
What are the wide opening caps and special caps used for?
wide-mouth cap is a cap used on containers with relatively wide openings, and is applied to large-capacity bottled water bottles or food containers.In addition to
, we manufacture molds of various sizes and structures, including oval one-touch caps, dome caps, PET insert molds, 32mm·36mm·38mm cap molds, and 66mm seasoning container cap molds.
Why are injection molding equipment important?
Injection molding is a production method that heats and melts plastic raw materials, injects them into a mold under high pressure, and cools them to shape the product.
Cap products are often small in size and complex in structure, so their quality may vary depending on injection pressure, temperature, cooling time, and mold precision.
Therefore, if a company producing precision cap molds has its own injection molding equipment , it can proceed with trial production immediately after manufacturing the mold.
During the test injection process, you can check the product's deformation or shrinkage, assembly condition, opening/closing feeling, sealing force, etc.
When problems are discovered, molds can be quickly reworked and retested, helping reduce development time and increase product maturity.
How is Taeyoung Corporation’s injection molding equipment structured?
Taeyoung Corporation operates electric injection molding machines of various specifications for its own injection production.
The main facilities currently announced are as follows.
- LS Mtron Electric Injection Molding Machine 330T 1 unit
- LS Mtron Electric Injection Molding Machine 280T 1 unit
- LS Mtron electric injection molding machine 220T 1 unit
- LS Mtron electric injection molding machine 170T 1 unit
- Toyo Korea Electric Injection Molding Machine 230T 2 units
Having injection machines with different clamping forces allows you to select the appropriate equipment according to the size, structure, and mold size of the product.
It is possible to operate facilities suitable for production conditions, from relatively small cap products to multi-cavity molds that produce multiple products simultaneously.
electric injection machine can control injection speed, pressure, and position relatively precisely, which is advantageous for reducing standard deviation and increasing the stability of repeat production.
Especially in the production of cap products that require precise shapes such as screw structures or hinge structures, it is important to maintain consistent injection conditions.
What are the advantages of our own injection production system?
If mold making and injection production are separated, schedules must be coordinated with an external company for trial production, and it may take a long time for modifications to be reflected.
On the other hand, if you operate your own injection production system like Taeyoung Corporation, test injection and quality verification can be continuously carried out internally after mold production.
The first advantage is the speed of development response.
The development process is efficient because test injection can be performed immediately after manufacturing the mold and the design can be modified according to the product status.
The second advantage is quality control.
Mold designers can directly check the actual injection product, allowing them to quickly identify various problems such as product deformation, short shots, flash, and shrinkage.
The third advantage is mass production stability.
Injection conditions and mold data obtained from pilot production can be reflected in the actual mass production process, helping to maintain consistent quality.
The fourth advantage is customized response.
The mold structure and injection conditions can be adjusted according to the container size, purpose of use, and cap opening/closing method, allowing us to respond to various customer needs.
What is the process from mold design to production?
cap mold production generally proceeds in the following order: product consultation, design, processing, assembly, test injection, modification, and preparation for mass production.
First, we check the size and purpose of the cap desired by the customer, how to combine the container, and production quantity. After
, product structure and mold are designed using CAD and CAM.
At the design stage, cap thickness, threads, hinge structure, sealing structure, cooling method, and product discharge method must be considered.
Once the design is completed, the mold parts are precision machined and assembled.
The completed mold is mounted on an injection machine for trial production, and the appearance, dimensions, and assembly state of the actual product are checked.
If necessary, modify the mold and adjust the injection conditions repeatedly, then check the final quality and proceed to the mass production stage.
Taeyoung Corporation operates this process organically through internal technology and its own facilities.
What are Taeyoung Corporation’s quality and technological competitiveness?
Taeyoung Corporation has acquired various certifications and established a research and development base to strengthen its technology and quality management system.
Representative examples include ISO 9001 quality management system certification, INNO-BIZ designation, venture business certification, and recognition of a dedicated research and development department.
ISO 9001 is a quality management certification that shows that product production and quality control processes are operated according to certain standards.
INNO-BIZ is a system designated for small and medium-sized businesses with technological innovation capabilities, and the operation of a dedicated research and development department serves as the basis for continuous product development and technological improvement.
Taeyoung Corporation invests in technical personnel and production facilities every year and continues research to improve mold quality and product durability.
Why is safety management important in the operation of injection molding equipment?
injection molding machines operate at high temperatures and pressures, and the weight of the mold is large, so systematic safety management is required.
When operating equipment, interlocks, optoelectronic protection devices, and emergency stop devices must be checked to prevent workers from accessing hazardous areas.
During mold replacement or facility maintenance, it is important to cut off the power and apply a lock to prevent the machine from operating suddenly.
Daily inspection is also required to check the condition of equipment, hydraulics, electrical devices, safety sensors, and mold fixation before starting work.
Accurate work procedures and regular facility inspections are important factors not only for worker safety but also for maintaining product quality and production efficiency.
What is the reason for growing into a global cap mold company?
Taeyoung Corporation has been doing business with overseas customers for a long time based on the experience it has accumulated in the domestic cap mold market. We have a variety of overseas export experience, starting with exporting
cap molds to the United States and supplying double injection cap molds to India.
In overseas transactions, design responsiveness and production stability are important because the product specifications and quality standards required by each country and company are different.
TAEYOUNG CAP MOLD is developing products to meet customer specifications based on its experience in producing various cap designs and its own injection production system.
Taeyoung Corporation aims to become a precision cap mold specialized company that continues for 100 years based on technological innovation, quality management, and trust with global customers.
