Heatsink HTK
Cooling Rod HTK: Provides fast cooling using a refrigerant as a heat exchange medium. Offers excellent thermal responsiveness, stability, and reduced maintenance.
Superior performance in plastic injection molding begins with high-grade Injection Mold Components. We understand that downtime is the enemy of profitability, which is why our mold parts are engineered for extreme thermal stability and minimal friction. From ejector systems to cooling components, we provide the building blocks for high-cycle production.

Plastic mold components (Injection Mold Components)are specialized parts used in plastic injection molding. They shape and form molten plastic into desired shapes. Examples include cavity inserts, sprue bushings, ejector pins, gate systems, cooling channels, and more. These components ensure accurate, consistent, and high-quality plastic parts.

Professional Sprung Core Solutions for Internal Undercuts
Factory Direct: Professional manufacturer offering OEM/ODM & custom machining services.
High Compatibility: 100% interchangeable with Cumsa, HASCO, and standards.
Space-Saving: The ideal solution for releasing internal grooves and undercuts in compact mold designs.

FlatCore Blades ULBFeatures: Used in conjunction with ULG and ULC, the length of the slanted top can be customized.

Internal Latch Lock DKLFeatures: Unique built-in device, different functions according to different installation methods, with internal locking buckle and secondary ejection function, can avoid conflicts between water transport and external installation parts.

Our company was established in 1998, specializing in the production of mold parts: collapsible core, slide retainer, date stamp, air valve, sprung core, latch lock, two-stage ejector, accelerated ejector, cooling circuit plugs and non-standard parts according to your drawing. Contact number: +86-769-83600929.

Features: The clamping buckle is a precision device, please install it symmetrically, otherwise it will cause the force of the single set of clamping buckle to be unbalanced, which will cause the clamping buckle to break.

Features: The independent design and precise scale ensure high precision in the first opening of the mold; it is more cost-effective than the traditional clamping buckle and optimizes the mold structure.

Product features: KL clamping buckle is only half of the complete set, it needs to be used with the other half of Ku (Ku needs to be ordered separately).

Features: Eliminates the possibility of breaking the mold, as there is no need for any changeable adjustments or links that may be accidentally knocked out. Suitable for general or heavy-duty molds, each mold requires a minimum of four clamping buckles.

Features: Through the hook-shaped locking pin, the structure of the repetitive action of the bolt makes the product small and saves the installation space, and can also be used for the ejection board to eject.

Features: In the mold processing, the same stroke symmetrical installation must be calculated; otherwise, the single set of clamping buckles will be unbalanced, and the components will be broken.

Push Locks Z4Features: simple installation and processing, mechanical interlock design, safe and reliable, can choose the corresponding product according to the mold load, at least two sets of molds should be used symmetrically, the use temperature range is 120 ¡ãC. Note: In the mold processing, the same stroke symmetrical installation must be calculated, otherwise the single set of clamping buckles will be unbalanced and the components will be broken.

Latch Locking Unit Z174Features: simple installation and mechanical interlocking design, safe and reliable, can choose the corresponding product according to the mold load, at least two sets of molds should be used symmetrically, the temperature range is 120 ¡ãC.



Features: Compared with other clamping buckles, it is easier to install and requires less speed reduction during mold clamping, thus shortening the molding cycle.
Our pins and bushings undergo specialized vacuum nitriding to achieve a hard outer shell, preventing galling and seizure under high-temperature continuous operation.
By utilizing premium heat-work steels and copper alloys, our components facilitate faster cooling rates, potentially reducing injection cycle times by up to 20%.
Manufactured on high-precision CNC grinders, our components follow strict DIN, ISO, and JIS standards, ensuring 100% fit-and-play during mold maintenance.
We offer customized heat treatment reports and material certifications, matching the specific resin requirements of your project (e.g., abrasive or corrosive plastics).
Send us your BOM or technical drawings for a detailed quotation and expert material advice within 12 hours.
Medical & Healthcare: High-precision components for cleanroom-grade syringe molds and diagnostic device housings.
Consumer Electronics: Critical parts for thin-wall molding of smartphone frames and micro-connectors.
High-Speed Packaging: Durable ejector and venting solutions for multi-cavity bottle cap and thin-wall container molds.
A: We provide specialized venting pins and porous metal inserts that allow gas to escape while preventing flash, significantly reducing gas burn defects in plastic parts.
A: Yes, we specialize in non-standard components. We can process STP, STEP, or IGS files and maintain tolerances as tight as 0.002mm for custom cores and cavities.
A: We suggest regular inspection of lubrication channels. For cleanroom applications, we provide DLC-coated or self-lubricating graphite components that operate without oil to prevent product contamination.
