Bottle Manufacturing

From natural ingredients through MC Glass bottle making process, we take shape glass packaging using advanced equipments, expertise and high quality standard to streamline manufacturing process and save the real costs

Professional Glass Bottle Manufactures from China

Inside MC Bottle glass making factory, we combine all natural raw material elements with cullet adding fire output pure glass vessels.

Qualified glass bottles are delivered to food, beverage, perfumery and pharmaceutical manufactures for filling. Bottled containers are on shelf in shop, after consuming, empty bottles are collected changing to cullet for next processing.

That is the recyling circle.

step by step

Manufacture process

Through plant equipments, raw material mixing station, furnace, refiner, forehearth, feeder, forming machine and aneealing lehr, a glass bottle is made.

A molten glass drop turns into beautiful glass container, we fulfill quality control throughout.

Combining
Step 1
cullet
Combine raw material and cullet

The main elements for glass are silica sand, soda ash and limestone. Other is recycled glass called cullet.

Weight and mix all natural raw material and cullet into a batch mixture then transfer into furnace for melting.

Melting
Step 2
melting into liquid glass
Melt raw materials

Melt all the conbined raw materials to 1565 degree Celsius, creating a liquid glass mixture.

The furnace is heated by gas and electricity running 24 hours a day, 7 days a week.

Cutting
Step 3
gobs
Cutting molten glass into gobs

The molten glass flows to refiner then split into small streams to the forehearth.

Cutting molten glass into gobs when cooled to a uniform temperature. The gobs are automatically sent to forming machine.

Forming
Step 4
moulding
forming and moulding

Glass gobs are diverted into moulds within the forming machines.

The gobs are dropped into  a blank mold to get the rough shape then transferred by forming machine to a second mould creating a final shape.

Annealing
Step 5
glass bottle annealing process
Annealing formed bottles

Reheating the formed bottles in lehr and gradually cooled.

The formed glass bottles go through the annealing lehr to be reheated and cooled down more slowly to release stress.

Inspection
Step 6
inspecting glass bottle visually before packing
Inspect automated and manually

Bottles go through inspecion devices then checked by human visually to eliminate defective bottles.

Rejected bottles are re-melted in next batch.

Packing
Step 7
palletize bottles
Packing in pallets or cartons

Qulified bottles are packaged in pallets or cartons for storage and shipped to customers.

Exporting standard cartons are custom sized as per client's requirement with sea transportation the destination port.

Got a Question?

F.A.Qs

Cullet proportion to be mixed in the batch influences the transparency and color of glass, also the purity of silica sand does.

Cobalt need to be added in to the clear glass during production to make original blue color without paint or film. Cobalt is rare material and expensive used in manufacturing. Also not so many factories produce true blue glass bottles.

The glass bottle factory will operate and keep making process 24 hours a day, 7 days a week since the furnace need to keep burning all times. Shutting down can cause fire resistant blocks to break.

We catagory the quality defects as critical, major defects and minor. During glass bottle manufacturing process, corrective actions should be taken to meet high standard level make bottle defects free. Read our blog to explore more.
