Preform Molding Auxiliary Machines
A complete preform molding system relies on efficient and stable auxiliary machines. They provide dry, clean raw materials, stable cooling, and power support for the injection molding machine, which is key to ensuring continuous and automated operation of the production line.
PET Preform Molding Automatic Drying & Feeding System
The automatic drying and feeding system continuously supplies fully dried PET material to the injection machine. As PET is highly sensitive to moisture, this system uses precise temperature control and dehumidification to ensure moisture content is minimized, fundamentally preventing issues like preform yellowing, bubbles, or strength reduction caused by damp raw materials.
PET Preform Molding Centralized Chilling Water Supply System
The centralized chilling water supply system provides stable, constant-temperature cooling water for multiple injection machines and molds. Through precise temperature control, it significantly shortens the preform molding cycle, improves production efficiency, and ensures uniform preform crystallinity and stable quality.
Centralized Clean Air Supplying System
The centralized clean air supplying system delivers stable, dry, oil-free, and constant-pressure compressed air for pneumatic components (such as robots and mold movements) throughout the workshop. This reduces equipment failure rates, ensures movement precision, and extends equipment service life.
Preform Molding Out-Mould Cooling System
The out-mold cooling system is responsible for removing the hot preforms from the mold and further cooling them to set their shape. This is crucial for high-cavity production, as it effectively frees up mold occupancy time, further increasing production capacity.
Out-Mould Preform Pick Up &.Cooling Robot
The DKM out-mold preform pick-up and cooling robot accurately extracts preforms from the mold and transfers them to the cooling conveyor or cooling station. Its movements are high-speed and smooth, and it can be integrated with a vision inspection system for preliminary screening of defective products.
Out-Mold Preform Pick Up &.Cooling Conveyor Belt
The cooling conveyor belt receives preforms from the robot and transports them at a uniform speed to the collection point. During transportation, the preforms cool naturally in a controlled environment, preventing deformation caused by rapid or uneven cooling.
Bottle Blow Molding System
The blow molding system transforms the molded preforms into the final desired bottle shapes through heating, stretching, and blowing processes. DKM blow molding machines are renowned for their high efficiency, low energy consumption, and excellent control over bottle wall thickness.
PET Bottle Blow Molding Machines
DKM’s fully automatic PET blow molding machines are suitable for producing various specifications of water bottles and beverage bottles. They feature advanced linear heating technology for uniform preform heating and a patented stretch-blow mechanism that ensures excellent bottle verticality and pressure resistance.
Small Bottle Blow Molding Machine
Designed specifically for producing small-capacity water and beverage bottles under 500ml, this machine boasts a very high production cycle rate to meet the huge market demand for small packaging bottles.
Wide-Mouth Blow Molding Machine
Specifically designed for producing wide-mouth jars and bottles, such as those for juice and sauces. Its special molds and blowing technology perfectly form containers with larger openings, ensuring a smooth, round finish and excellent sealability.
5-Gallon Water Bottle Blow Molding Machine
Designed for the production of large-capacity 5-gallon water bottles, this machine features high clamping force and blow pressure to ensure uniform wall thickness, high pressure resistance, and impact strength, making it ideal for the bottled water dispenser market.
Oil Bottle Blow Molding Machine
Suitable for producing cooking oil bottles. This machine places special emphasis on bottle clarity and sealability to ensure the safe storage of oil. It can produce shaped oil bottles with handles to meet diverse market demands.
Cap Molding System
The cap system delivers integrated solutions from preform molding to post-processing. DKM provides injection molding technologies for cap production, meeting diverse customer requirements for cap types, cost efficiency, and production performance.
Cap Injection Molding Machine
The cap molding system provides a complete solution from cap forming to post-processing. DKM offers both injection and compression molding technologies to meet different customer requirements for cap type, cost, and efficiency.
Cap Compression Molding Machine
The cap compression molding machine is ideal for producing high-performance caps (e.g., for carbonated beverages). Compression-molded caps have low internal stress, excellent sealing performance, and offer material savings.
Cap Flanging Machine
This machine is used to flange the molded cap preforms, forming structures like tamper-evident bands that interface with the bottle neck. It features a high degree of automation and ensures precise and consistent flanging dimensions.
Cap Cutting Machine
This machine is used to separate interconnected caps produced by multi-cavity molds. It offers high cutting speed and creates smooth, clean cuts without damaging the caps, making it a crucial piece of post-processing equipment in automated production lines.
