Bottle Moulds: The Ultimate FAQ Guide

I know choosing appropriate bottle moulds can be a challenge.

A reason this guide explores everything you need to know about bottle molds – from features, material, features to specifications.

Keep reading to learn more.

1.  What Are Bottle Moulds?

Bottle Moulds are tools that enable you to obtain bottles of a chosen shape from molten glass. These tools have been developed and improved for centuries.

The main development has been in glassmaking technology as well as increasing precision. That technology leads to better quality bottles and lowers costs.

These Bottle Molds are moulds that are used to create the bottle shape. They come in two halves which are joined together by a pour spout.

Air bubbles are easily removed as they travel up the vertical tubes of the molds!

Bottle Moulds

Bottle Moulds tooling systems are the most advanced molding systems today because they offer the highest quality, lowest cost solution to rigid plastic container production.

Bottle moulds are the perfect way to create bottles from chocolate, plaster, candy, or ice. They’re available in several sizes and styles, including shaker bottles and mini mason jars.

2.  What Materials Can You Use For Bottle Moulds?

Depending on what you plan to do, you can use various mold-making materials. Below, we will look at several of these materials and how they perform.

These bottle moulds are normally formed by clay, aluminum, plastic, glass, and other water-resistant materials. Bottle molds can be made from seven different materials.

        i.            Metals

The most common type of bottle mold is metal bottle mold. These are used for food containers and plastic bottles. Steel and aluminum are mostly used as manufacturing materials for bottle moulds.

3.  What Popular Methods Used For Bottle Moulding?

There are many methods used for bottle moulding, but the most common and efficient methods are given as follows:

        i.            Extrusion Molding

In Extrusion Molding, a long strand of material (extruded material) is used to produce a specific function. This process works for all kinds of plastics and some thermo-plastics.

A multi-layer plastic tube or a foam profile is formed in one or several steps by applying consistent pressure to the extruded material.

Extrusion Moulding

      ii.            Injection Moulding

Injection molding works by injecting warm liquid plastic into a mold cavity and then cooling it to produce the bottle mold fully formed.

The injector machine applies pressure in the cavity backward and forward until the plastic cools and solidifies.

Injection moulding

    iii.            Compression Molding,

Compression molding is like injection molding but uses a lower temperature of plastic that requires less pressure to compress the molten plastic into a mold cavity.

The molten plastic is then pushed into the cavity using heated metal tools called pins or pistons.

    iv.            Blow Molding

The blow molding process makes bottles out of high-density polyethylene (HDPE). Blow molding is a process that makes hollow pieces of plastic by blowing air into them.

Blow Moulding

      v.            Injection Molding

Injection molding is a manufacturing process for producing plastic parts. That requires molds to shape the material in a form that can be removed after cooling.

    vi.            Rotational Molding

The bottles are heated, stretched, and rotated during the molding process and quickly cooled under pressure, so seams are virtually eliminated.

Using rotational molding is a smart way to create durable and attractive products perfect for your personal needs.

  vii.            Transfer Moulding

Transfer molding uses two molds and transfers paper. A top or bottom half of a mold is used to stabilize your original design while creating an opposing replica, which is transferred onto the opposing half of the plaster or wax model.

4.  How Do You Make Bottle Moulds?

The production process is fascinating, from the starting materials to the cooling and ejecting of bottle moulds.

Several processes are involved in making moulds that require high technology and hand skills.

Making bottle moulds varies depending on the products and the machinery available. The steps of making bottle molds are simple, given in the points below.

i. First, a sculptor creates a plaster model of the design

ii. Generate a CAD drawing of the bottle shape

iii. After that, send it to the CNC for cutting

iv. Put the two parts of the mould together to check if they fit

v. Start injection/production

vi. Quality control – this step is highly recommended because more and more bottle moulds are rejecting due to poor quality.

vii. Next, the required material is poured into the mould and allowed to cool and harden for several days

viii. Then, it’s removed from the plaster mold, smoothed out around all the edges, painted, and ready for use

5.  Which Techniques Can You Use To Make Bottle Moulds?

There are three basic techniques used to make bottle moulds. These include head-first, body-first, and lastly, the lost wax technique. All three of these mould creation techniques have their benefits.

If a great deal of investment is to create the bottle mould and make the glassware that can be made from it, then head-first is ideal.

It will involve creating a full figure mould and all relevant smaller sections, such as lugs or a collar.

The below-given table shows the various benefit of each technique, including extrusion bottle moulding (EBM), Compression bottle moulding (CBM), Injection Bottle Moulding (IBM), and Injection Stretch Bottle Moulding (ISBM).

6.  What Types Of Bottles Can You Make With Bottle Moulds?

There are various types of bottle moulds available to suit your style. Flexible ones allow you to remove your work and decorate it at any stage while still flexible.

You can then use these to make a vase or other item with a narrow opening.

Glass Bottle Moulds are slightly more rigid, making them ideal for creating glass bottles with straight sides.

Some of the common products of the bottle mould are given as follows:

• Plastic Bottles
• PET blank bottles
• Cups
• Glass Bottles
• Jars
• Perfume oil bottles
• Essential Oil Bottles
• Bathroom essentials bottles
• Ice-Cream Cups
• All Kind Of Beverages Bottles
• Water Cans
• Metal Tin

7.  What Are The Applications Of Bottle Moulds?

Bottles molds are used in multiple industries due to their wide consumption and requirements. The main applications of bottle molds are given as follows:

        i.            Beverage Bottles

Bottle Molds are used in the industries that are manufacturing beverages bottles. This mold comprises 2 or more cavities, giving shape to the bottle.

A cavity is a compartment-like structure designed to make the shape of the bottle by different kinds of machines.

Every year there has been an increase in the demand for molds. Due to its growing demand now, different shapes of molds are available in the market.

      ii.            Domestic Industrial Chemical

Bottle molds are crucial for in-household industrial chemical (HIC) production. HICs are chemicals drawn from households and industries.

When it comes to HICs, most people want the best quality without paying extra. They are produced with stainless steel or aluminum to resist corrosion in the HIC industry.

Bottle Molds can also be made from other metals like iron, steel, brass, and bronze as per the application requirements.

    iii.            Personal Care

Bottle molds are important for making bottles for personal care products. The plastic is molded into different shapes and sizes, creating an effective package that keeps water, antiperspirants, lotions, and hair spray fresh.

The most common bottle molds are J-shaped, C-shaped, hollow cubes with a flat surface at each end and other shapes.

    iv.            Motor Oil Industries

Bottle molds are used in the manufacturing of motor oil bottles. They are a specific type of mold that is made to be used in the production of another item.

They are unique items that serve a particular purpose and often need to be fitted precisely to provide their intended service.

8.  Are There Custom Bottle Moulds?

Yes. Bottle molds can be made with inserts to accommodate your specific bottle shape. It is great because it means you will have the perfect bottle mold for any bottle.

Molds can also be made with adjustable plates to create molds with inserts for one or multiple bottles simultaneously.

While every bottle has its shape and size, so do its moulds. Bottles can be viewed as shapes of regular polygons- square, rectangle, triangle, or circles.

9.  How Personalized Bottle Moulds Assist In Effective Branding?

Bottle moulds assist in effective branding to draw your company or product out of the dense market competition.

As a means of marketing and product promotion, personalized bottle moulds are attractive and efficient in cost and effort.

A personalized bottle mold can be imprinted with the name, logo, and design required by the manufacturer. The cost of such a product needs to amount of series as well as this ensures accuracy.

10.  What Types Of Machines Used In Bottle Moulds?

Bottle Moulding Machines are mainly used to create large quantities of bottles, cups, and other containers.

They are designed to produce in volume with smaller tooling investment and short change-over lead times.

Although the machine can be adapted for various products, Bottle Moulding Machines are mainly used to create plastic jars, cups, or water bottles from PET, PP, HDPE, etc. Carbonated drinks bottles are also produced on this machine.

There are three highlighted and most famous machines used for bottle moulds which are given as:

        i.            Injection Moulding Machine

Injection moulding machines are used to produce plastic containers, and several techniques can be used, but the most common are single cavity injection moulding.

Different techniques are adopted in the design of bottle mould designs. A combination of locks will open the mold after ejection to avoid drooping and allow coolant spray to reach all surfaces.

Injection Moulding Machine

      ii.            Extrusion Moulding Machine

Extrusion blow moulding is like injection moulding because it has a die and a barrel.

Both contain a screw and differ because the barrel is heated while blow air is forced into the barrel instead of being heated or chilled.

That causes the molten plastic material to cool and harden. Whether you’re looking for a plastic bottle mould or any blow molding, Bottle Moulds will be able to help you find what you need amongst its vast product range.

Extrusion Moulding Machine

    iii.            Blow Moulding Machine

The most common bottles and jars produced by blow moulding are soap bottles, shampoo bottles, and mouthwash bottles.

To make these products, the machine first heats a long glass tube to about 200°C. Then inserts, it into two steel molds that look like a large sandwich with somewhat convex pieces of thin glass.

As the tube is drawn through the molds, the glass in contact with the steel causes it to bend down and form a container shape. Finished containers are cooled before being filled with product.

11.  What Are The Components Of Bottle Moulding Machine?

There are multiple bottle molding machines in the market, but we will discuss the blow molding machine components. Due to its extensive usage in the industry, it’s important to discuss the components of this machine which are given as follows:

        i.            Feeding System

This system comprises the electronic and steering system of the machines. This machine has a hopper, transporter, gravity railings, and Orientation. The raw material is fed into machines through this feeding system.

      ii.            Perform Tilter

If the bottle moulds need to be produced from PET, this component allows the machine to supply the raw material continuously.

    iii.            Bottle Exit Conveyor

This part of the machine could be different depending on the design of the bottle mould. It helps the movement of bottles towards the filler or separating system.

    iv.            Compressor Station

Plastic bottles are compressed into an extremely rigid structure in this machine section. The compressor station comprises different parts that work together to pump compressed air into the tanks.

      v.            Water Cooling System

This part helps reduce the heat generated during the bottle moulding process through water cooling.

12.  What Is The Difference Between Silicone And Glass Bottle Moulds?

There is a significant difference between the two types of bottle moulds available. Some of the main highlighted points are given as follows:

13.  What Size And Capacity Of Bottles You Can Manufacture With Bottle Moulds?

If you are looking for a small-scale factory, you can make 10-20 different moulds for your bottle. The capacity of the bottle is about 300ml-1500ml, and it depends on the size of your bottle.

Bottle moulds will hold fluid up to 25 liters. These machine moulds produce baby milk, fruit juices, teas, syrups, and other drinks in glass bottles.

The capacity of bottle moulds is usually up to 7000-8000pcs/hour.

14.  Why Should You Import Bottle Moulds From China?

Mould quality and delivery time issues, back-orders, and hassle of finding suppliers. Buying moulds is a gamble; you buy them without knowing their quality and whether they’ll arrive on time.

More and more businesses are discovering the benefits of using bottle molds imported from China. Their body shapes offer more options than European moulds.

At present, China is the most important bottle mould manufacturing country globally. Bottle moulds are the equipment that mold bottles, and therefore they are an extremely important component of the entire bottling production line.

At present, bottle moulds produced in china number more than 2,000 sets and occupy a large proportion of the market.

15.  How Using Air Filter In Bottle Molding Is Beneficial?

Air filters clean up the released air after plastic bottles are molded. Changing or replacing the filters every couple of months or even once a year is necessary if you mold many bottles.

The time required for replacing a filter varies from one to another. While some can last for about eight months, others may need replacement within three months.

These air filters solve several issues given below:

1. They prevent external dust from entering the molding system.
2. They remove dust generated during the production cycle.
3. They help avoid potential problems with the formed product, such as dry spots or distortion caused by clogged pores.

16.  How Does The Design Of Bottle Mold Affect Its Overall Strength?

No matter how expert your design and detail, if your mould is not made with the right material, it simply would not be able to last a long time.

If you research online, many mold manufacturers proudly display the material they use to build a certain type of mould. It helps you shortlist different brands and find the one perfect for your application.

The design of the bottle mould affects its overall strength.

As a bottle mould is used to produce hundreds of bottles, it will undergo many heating and cooling cycles.

Also, the mold undergoes multitudes of stress in every production process. Some of the most common stress on bottle moulds would be tensile stress, compressive stress, splitting force, and thermal stress.

Any one of these stress alone may affect mould function but, when combined among themselves, may cause a large amount of damage

17.  What Design Should You Choose For Bottle Moulds?

There is so much more to pick than just a design when purchasing your bottle moulds. You need to consider and use many factors to determine which bottle moulds are best for your needs.

The designs on the bottle moulds make all the difference, but there is more to consider before making that big purchase.

You need to examine your business first and then ask yourself how much use you will get from the product.

This will help you determine how many molds are needed in your workflow.
