Plastic vs Cast Iron Concrete Cube Mould – Which Is Better for Your Laboratory? Malaysia
Plastic vs Cast Iron Concrete Cube Mould – Which Is Better for Your Laboratory? Malaysia
Introduction
When purchasing a Concrete Cube Mould, one of the most common questions is:
“Should I buy a Plastic Cube Mould or Cast Iron Cube Mould?”
Both types can be useful, but they serve different operational needs. Plastic moulds are attractive for portability and corrosion resistance, while cast iron moulds are preferred where rigidity and heavy-duty laboratory use are priorities.
The best choice depends on your testing volume, working environment, required specimen size, applicable testing requirements, maintenance capability, and budget.
At MTM Precision Sdn. Bhd., we supply Plastic and Cast Iron Concrete Cube Moulds together with a broader range of Construction Material Testing Equipment throughout Malaysia.
What Is a Plastic Concrete Cube Mould?
A Plastic Concrete Cube Mould is manufactured from a suitable rigid plastic material and designed to prepare concrete cube specimens.
Common nominal sizes can include:
100 × 100 × 100 mm
150 × 150 × 150 mm
Plastic moulds have become popular for construction-site and routine testing applications because they are significantly easier to handle than traditional heavy metal moulds.
Advantages of Plastic Cube Moulds
Lightweight
This is one of their biggest advantages.
When technicians need to carry several moulds around a construction site, the difference in weight can become significant.
Plastic moulds are especially convenient for:
Site technicians
Mobile testing teams
Contractors
Ready-mix concrete companies
Corrosion Resistant
Plastic does not rust like ferrous metal.
This is particularly useful in Malaysia's humid environment and for moulds that are frequently exposed to water during cleaning and concrete specimen preparation.
Easy to Transport
For testing teams moving between projects, lightweight moulds simplify transportation.
A vehicle carrying many plastic moulds will generally have a much lower mould weight than if the same number of heavy cast iron moulds were transported.
Suitable for Larger Quantities
Ready-mix plants and contractors sometimes require many moulds simultaneously.
Plastic moulds can be a practical choice where:
Many samples are prepared
Moulds move between locations
Storage space is limited
Handling efficiency is important
What Is a Cast Iron Concrete Cube Mould?
A Cast Iron Concrete Cube Mould is a heavy-duty metal mould designed for repeated concrete specimen preparation.
Its major advantage is rigidity.
Cast iron moulds are commonly considered for:
Commercial laboratories
Permanent site laboratories
Ready-mix QC laboratories
Precast laboratories
Universities
Research facilities
Advantages of Cast Iron Cube Moulds
Excellent Rigidity
Cast iron provides a very rigid mould structure.
This helps the mould maintain its geometry during specimen preparation and repeated use.
Heavy-Duty Construction
A properly manufactured and maintained cast iron mould can withstand frequent laboratory use.
This makes it attractive to laboratories preparing specimens every day.
Dimensional Stability
For professional laboratory operations, maintaining suitable mould dimensions is important.
Cast iron moulds can provide excellent dimensional stability when manufactured correctly and maintained properly.
Long-Term Laboratory Use
Although the initial purchase price and weight may be higher, durability can make cast iron attractive for high-volume users.

There is no universal winner.
The correct choice depends on the application.
Which Is Better for Construction Sites?
For mobile site testing, plastic cube moulds can often be the more practical choice.
Construction personnel may need to:
Carry moulds between floors
Move between pouring locations
Transport moulds between projects
Work in temporary site laboratories
Handle many moulds simultaneously
Lower weight becomes a significant advantage.
Which Is Better for a Permanent Laboratory?
For a permanent material testing laboratory, cast iron can be an excellent choice because portability is less important.
Laboratories may prioritise:
Rigidity
Durability
Repeated use
Dimensional stability
Heavy-duty construction
In this environment, the additional weight is usually less of a disadvantage.
Which Is Better for Ready-Mix Concrete Plants?
Ready-mix companies may benefit from using both.
Plastic Moulds
Useful for:
Customer construction sites
Mobile sampling
Larger quantities
Easy transportation
Cast Iron Moulds
Useful for:
Permanent QC laboratory
Repeated testing
Heavy-duty operation
A mixed mould inventory can provide more operational flexibility.
Which Is Better for Precast Factories?
Precast factories generally operate from fixed production locations.
Therefore, heavy-duty cast iron moulds can be attractive for the factory laboratory.
However, plastic moulds may still be useful when:
Many specimens are required
Moulds are moved around the production facility
Lightweight handling is preferred
The best combination depends on production volume and internal QC procedures.
Which Is Better for Universities?
Universities may have two different requirements.
Teaching Laboratories
Plastic moulds can be convenient because they are easier for students to handle.
Research Laboratories
Cast iron moulds may be preferred for repeated professional-level specimen preparation.
Many civil engineering departments can therefore benefit from having both types available.
What About Mould Life?
The working life of either type depends heavily on:
Manufacturing quality
Usage frequency
Cleaning procedure
Storage
Handling
Inspection
Maintenance
A cast iron mould is not automatically permanent, and a plastic mould should not automatically be considered disposable.
Both should be inspected regularly.
When Should a Plastic Cube Mould Be Replaced?
Consider removing a plastic mould from service if you find:
Cracks
Distortion
Damaged corners
Excessive wear
Damaged internal surfaces
Loss of required dimensions
Do not continue using a mould simply because it can still physically hold concrete.
When Should a Cast Iron Cube Mould Be Replaced?
Watch for:
Severe corrosion
Distortion
Worn contact surfaces
Damaged fastening components
Poor alignment
Internal dimensional problems
Some components may be maintainable or replaceable depending on mould construction.
Which One Is Cheaper?
Plastic moulds may have a lower initial cost in many configurations, but purchase price alone does not determine value.
For a professional laboratory, consider:
Purchase Cost ÷ Useful Number of Specimen Preparations = Approximate Cost per Use
A more expensive mould that provides a long service life may be economical over time.
Should You Buy Both?
For some customers, yes.
A practical arrangement can be:
Plastic Cube Moulds → Site & Mobile Testing
Cast Iron Cube Moulds → Permanent Laboratory Testing
This provides flexibility instead of forcing one mould type to serve every application.
Don't Forget the Required Cube Size
After deciding between plastic and cast iron, you still need to determine the correct specimen dimensions.
Common nominal options include:
100 × 100 × 100 mm
150 × 150 × 150 mm
Selection should follow the applicable test method and project specification.
