Bottle Handle Mold (BHM) is a type of mould using to make handles for plastic bottles.They are usually work with Bottle handle injection molding machine.These moulds can be designed as side handles or carrying handles to allow people to carry liquid plastic bottles such as drinking water, cooking oil, sauces and beverages.
During the injection moulding process, the design of the mould needs to take into account factors such as gate position, filling time, pressure and cooling effect to ensure the strength and surface quality of the handle.
In addition, temperature control of the mould is also very important to avoid deformation of the bottle during demoulding.
Design of plastic bottle handle injection mould
Bottle Handle Mould The design of the injection mould is based on the details and output of the plastic bottle handle product.
There are seven key aspects specifically:
- Bottle handle material selection
- Bottle handle mould structure design
- Bottle handle mould pouring system design
- Bottle handle mould cooling system design
- Bottle handle demoulding mechanism design
- Bottle handle motion simulation and verification
- Application of software tools

Bottle handle material selection:
Commonly used plastic materials for bottle handles include ABS, PE, HDPE and PP.
These materials have good moulding and mechanical properties.
Bottle handle mould structure design:
The mould usually adopts the design of one mould with two cavities or multiple cavities to improve the production efficiency.
For example, the injection mould for plastic cups with handles adopts a one-mould two-cavity structure and feeds the material through a point gate.
Bottle handle mould pouring system design:
The design of the pouring system needs to ensure that the molten plastic can fill the mould cavity uniformly to avoid air bubbles and defects.
For example, submerged gates or side gates are used to feed the plastic.
Bottle handle mould cooling system design:
Cooling system is an important part of the mould design, usually using a ring cooling water circuit or in line with the cooling channel.
To shorten the moulding cycle and improve product quality.
Bottle handle mould release mechanism design
For plastic parts with complex structure (such as threaded or side holes), it is necessary to design the corresponding demoulding mechanism.
Such as oblique guide column, slide or push tube release mechanism.
Bottle handle motion simulation and verification
Verify the reasonableness and feasibility of the mould design through motion simulation
Ensure that the mould can work properly in the actual production.
Application of software tools
The design process can use CAD, UG, Moldflow and other software for three-dimensional modelling and process analysis.
To improve the design efficiency and accuracy.And work with Bottle handle injection molding machine smoothly.
The design of bottle handle injection mould needs to consider many aspects such as material selection, mould structure, pouring system, cooling system, demoulding mechanism and simulation verification to ensure the reliability of the mould and the quality of the product.
Bottle handle injection mould material selection type characteristics
Bottle handle injection mould material selection type characteristics mainly include material and performance requirements.
There are six aspects:
- Bottle handle injection mould steel
- Bottle handle injection mould tool steel
- Bottle handle injection mould aluminium alloy
- Bottle handle injection mould plastic mould steel
- Bottle handle injection mould special requirements
- Bottle handle injection mould comprehensive performance
Bottle handle injection mould steel steel
Steel is one of the most commonly used materials in injection moulds, with high strength, high hardness and good wear resistance.
It is suitable for the production of medium and high pressure injection moulds.
For example, P20 steel has good cutting performance and wear resistance and is suitable for low and medium pressure injection moulds.
H13 steel is suitable for high pressure injection mould because of its higher hardness and heat resistance.
Bottle handle injection mould tool steel
Tool steel is widely used for its high hardness, wear resistance and corrosion resistance.
Common tool steels include P20, H13, S136, etc. Among them, P20 steel is suitable for medium and low pressure moulds.
H13 steel is suitable for high pressure moulds and S136 steel is suitable for high requirement moulds.
Bottle handle injection mould aluminium alloy
Aluminium alloy is lightweight and has good thermal conductivity, but low strength and hardness.
It is suitable for small moulds or occasions that require rapid heat dissipation.
Bottle handle injection mould plastic mould steel
This material has lower cost and is suitable for small batch production and prototyping, but its strength and hardness are lower.
Bottle handle injection mould special requirements
In the selection of mould materials, you also need to consider the material and characteristics of the product, the use of the mould environment, service life, precision and surface quality requirements and cost and other factors.
Some plastic materials may require higher mould temperatures or greater pressure, so you need to choose materials that can withstand these conditions.
Bottle handle injection mould comprehensive performance
When selecting mould materials, key performance indicators such as hardness, wear resistance, thermal stability and corrosion resistance need to be balanced.
To ensure the stable operation of the mould and extend the service life.
The selection of materials for bottle handle injection moulds needs to be based on specific application requirements and production conditions for comprehensive consideration to ensure the performance and productivity of the mould.
