Different edible oil bottles require different preform weights, neck dimensions and wall thickness distributions.
ShuangLi can manufacture the mold according to your existing preform drawing or develop the tooling based on your bottle and closure requirements.
Customization can include:
Preform weight and dimensions
Neck diameter and neck finish
Thread and sealing structure
Preform length
Wall thickness distribution
Gate structure
Number of cavities
Mold dimensions
Injection molding machine compatibility
This allows the mold to be matched to both the final bottle design and the customer's production equipment.
The edible oil PET preform mold can be configured with different cavity numbers according to the required production capacity.
The appropriate cavity count is determined by several factors, including:
Preform weight
Required hourly output
Injection molding machine shot capacity
Clamping force
Tie-bar spacing
Mold dimensions
Cooling capacity
Production cycle requirements
For new projects, ShuangLi can help evaluate these factors before confirming the mold configuration.
A hot runner system can be configured for continuous PET preform production.
A properly designed runner and gate system helps distribute molten PET evenly between cavities and supports consistent filling across multi-cavity molds.
The system is designed with the goals of:
Balanced cavity filling
Stable preform weight
Consistent gate quality
Reduced runner material waste
Reliable continuous production
Hot runner configuration can be selected according to the mold structure and customer's production requirements.
Cooling performance is especially important in PET preform injection molding because it directly affects cycle stability, dimensional consistency and productivity.
ShuangLi designs cooling channels according to the preform geometry and mold structure to improve heat removal from critical areas of the mold.
An optimized cooling layout helps maintain more consistent mold temperatures and supports stable production across multiple cavities.
Critical mold components such as the core, cavity, neck ring and gate area require accurate machining because dimensional variation can affect the preform and subsequent blow molding process.
ShuangLi uses precision CNC machining and inspection equipment in the manufacture of preform molds.
Key components are manufactured and checked according to the confirmed drawings to support:
Consistent neck dimensions
Uniform preform geometry
Stable sealing surfaces
Accurate cavity matching
Repeatable production
For long-term production, mold maintenance and spare-part replacement are important considerations.
The mold structure can be designed to facilitate inspection and servicing of frequently maintained components such as:
Core
Cavity
Neck ring
Gate insert
Sealing components
Hot runner components
Replaceable mold components also make it easier to maintain production quality when individual parts become worn after extended operation.
This PET edible oil preform mold is suitable for manufacturing preforms used for packaging products such as:
Cooking oil
Vegetable oil
Sunflower oil
Soybean oil
Corn oil
Olive oil
Blended edible oil
Vinegar
Sauces and other food liquids
The mold can be developed for different bottle capacities and packaging formats according to the customer's bottle and preform design.

Final specifications should be confirmed according to the customer's preform drawing, bottle design and injection molding machine.
An edible oil preform mold should not be selected only by cavity number.
Before mold design is finalized, the mold must be checked against the actual injection molding machine to ensure suitable installation and production conditions.
For accurate mold configuration, please provide:
Injection molding machine brand and model
Maximum shot weight
Clamping force
Tie-bar spacing
Minimum and maximum mold thickness
Ejector specifications
Existing preform drawing, if available
Preform weight
Neck finish
Target production capacity
If you are starting a new edible oil packaging project and do not yet have a complete preform drawing, you can also provide the final bottle sample, bottle drawing or cap specification for evaluation.
ShuangLi specializes in the R&D and manufacturing of precision preform molds and provides customized tooling according to specific customer requirements.
A typical project can include:
1. Requirement Review
Confirm bottle application, preform weight, neck finish, cavity number, target output and injection molding machine information.
2. Mold Design
Develop the mold structure, cavity arrangement, runner system and cooling layout based on the approved product requirements.
3. Precision Machining
Manufacture mold components using CNC and precision machining equipment.
4. Assembly and Inspection
Check critical components and dimensions before mold assembly.
5. Mold Trial and Verification
Test the mold and inspect sample preforms according to the confirmed project requirements.
6. Delivery and Technical Support
Provide the completed mold and related technical support for installation, production and maintenance.
ShuangLi focuses on the R&D and manufacturing of precision preform molds rather than general-purpose plastic products.
This specialization allows the engineering team to focus on the requirements of PET preform production, including cavity consistency, neck precision, cooling and mold compatibility.
The company uses CNC machining and inspection equipment to control critical mold dimensions and component quality during manufacturing.
Each edible oil packaging project can have different bottle sizes, preform weights, closures and production targets.
ShuangLi can customize the mold according to the customer's actual packaging and production requirements rather than limiting projects to a fixed mold specification.
ShuangLi preform mold products have been supplied to customers in more than 50 countries, supporting packaging manufacturers in different markets and production environments.
The most useful information includes your preform drawing, preform weight, neck finish, target cavity number, required output and injection molding machine model.
If a complete preform drawing is not available, you can provide the bottle drawing, bottle sample and cap specification for further evaluation.
The cavity number depends on your required production capacity and injection molding machine.
A heavier edible oil preform normally requires more injection capacity per cavity, so cavity count should be calculated together with preform weight, machine shot capacity, clamping force and cooling conditions rather than selected independently.
Yes. The neck area can be developed according to the customer's bottle cap, neck drawing or existing preform specification.
Accurate neck dimensions are particularly important for cap fit, sealing performance and downstream bottle production.
Yes. Please provide the machine brand, model and technical specifications. ShuangLi can evaluate mold dimensions, cavity configuration and other key parameters according to the available machine.
A sample can be used as an important reference, but detailed drawings and dimensional information are preferred for accurate tooling development. If drawings are not available, contact ShuangLi to discuss the available samples and project requirements.
Whether you are developing a new cooking oil bottle or replacing an existing PET preform mold, ShuangLi can provide a customized tooling solution based on your preform specification, injection molding machine and production target.
Send us your preform drawing, bottle drawing, cap specification or existing sample, together with your required cavity number and production capacity, to receive a suitable mold proposal.
