China plastic cap mold manufacturer
olive oil bottle cap processing
From the overall structure and assembly drawing of the mold, the mold is mainly divided into two parts: the movable mold and the fixed mold. The olive oil bottle cap mold adopts a one-mold four-cavity structure, and the cavities are distributed in one piece, with a total of 4 cavities, but the shapes of the cavities are different. The gate is generally designed with a side gate.
Install the olive oil bottle cap mold on the injection molding machine, and then adjust the injection molding process. Required parameters. During the injection molding process, the plastic melt is injected into the mold cavity along the gating system at a certain injection pressure. After the mold is opened, fix the fixed mold part on the connecting plate. Move the fixed mold part backward.
01 Understanding Customer Needs
After understanding the requirements of the bottle cap, we can make the cap mold accordingly, such as considering the quality, material, cavity, price, delivery time, payment period, etc.
02 mold design
After being familiar with the specifications and requirements of the water bottle cap, our mold design team will make the best mold design. 2D & 3D mold design (CAD, UG, SolidWorks, ProE, etc., 2D drawings: DXF, DWG, PDF files, 3D models: IGS, PRT, XT, free electronic drawings.)

Why choose YUCO olive oil bottle cap mold
Oil bottle cap molds are widely used in daily life. Oil bottle caps are divided into food and non-food categories according to functional areas, such as edible oil bottle cap packaging and olive oil bottle cap packaging in food packaging. In the industrial field, they are used for automobile oil bottle packaging, automobile engine oil bottle packaging, and some CNC machine tool oil bottle packaging. According to the appearance, they are divided into flip-top series and two-part assembly series. The mechanism of the oil bottle cap usually has high requirements for the production process.

Frequently asked questions
Olive oil bottle cap mold design considerations
When designing the olive oil bottle cap injection mold, according to the structural characteristics, a 1-mold 4-cavity structure is selected. The olive oil bottle cap mold adopts a fixed mold core floating and secondary ejection structure to ensure smooth demolding. The upper and lower openings adopt an inverted structure.
In addition, the slider adopts a forced reset mechanism to lock the mold smoothly. After testing, the mold structure is reasonable and the produced plastic parts meet our quality requirements.
The olive oil bottle cap mold pouring system includes a main runner, a primary runner, a secondary runner, a tertiary runner and a gate. In this process, the sleeve is formed, the primary runner is processed on the fixed mold plate, and the secondary and tertiary runners are processed on the vertical parting surface. For ease of processing, the plate runner adopts a trapezoidal cross-section and the slider runner adopts a circular cross-section.
As part of the mold temperature control system, the fixed mold part is opened on the fixed mold plate, and the movable mold part is circulated and cooled by the baffle closing slider, and the mold temperature is kept within the required range by circulating cooling water. In the mold exhaust system, the air mainly acts between the baffle closing slider and the core, which is called gap flow.
