Sositar Mould celebrates 20th year in the injection moulding business

Injection molding, in principle, is a simple process. It involves designing a mold which contains a cavity in the shape of the product that has been designed. 

That product is often produced in plastic, which is initially melted and passed into the mold’s cavity.

Once cooled, the solid-state part is removed from the mold, and there you have it – the plastic part that you had originally designed. 

It can be a complex process, especially if you’re designing parts for the dashboard of a car. For example, the air vents, or even the entire dashboard casing, which dominates the entire front of a vehicle’s interior.

But whatever you’re requirements, Sositar Mould can certainly advise you, guide you through the design process if necessary, and produce the precise mold that you need to create the part that you have designed.


This year, Sositar Mould is celebrating its 20th anniversary – it’s been two decades since its establishment in 1998.

The company specialises in plastic molds for the following sectors:

  • automotive;
  • home appliances;
  • medical equipment;
  • electronics and sporting equipment; and
  • general industrial original equipment manufacturing applications.

Sositar’s factory covers more than 3,800 sq m of space and near to transport hubs in Shenzen, China, and has the capacity to produce 60-80 molds per month.

Offering its services online at a website called, Sositar says it is capable of making molds of quite large size.

“We are capable of producing injecting molded parts with weights up to 1500 grams or in presses up to 650 tons, building various kinds of plastic moulds and die casts ranging in size up to 8500 x 1000 x 8500 mm,” says Sositar Mould.


The molding and computer numerical control machines and equipment Sositar uses are mainly imported from Switzerland and Taiwan.

They include:

  • 21 milling machines (17 imported, and 4 domestically made);
  • 6 CNC machines;
  • 11 Charmilles electrical discharge machines;
  • 10 grinding machines;
  • 4 lathes;
  • 7 wire cutting machines;
  • 10 injection machines;
  • co-ordinate measuring machine;
  • video measurement system;
  • slow-feeding linear cutting machine; and
  • various auxiliary equipment.

Sositar Mould employs more than 150 “experienced toolmakers”, many of whom have been with the company since it started, and receive regular training to update their skills.

The company says it believes the quality of its employees is fundamental to ensuring high-quality products.

“We emphasize the development of both employees and company,” says a Sositar spokesperson. “We employ many experienced mold makers, and actively manage our talented and professional mould making engineers.”


In recent years, it has become increasingly important to work with companies around the world through the internet.

Some of the latest software enables collaboration in real-time online, so both the part design and the mold design can actually be done at the same time, ensuring higher quality and virtually eliminating the risk of misunderstandings.

Sositar offers a one-stop solution for customized and plastic parts production, and says it is constantly using web-based tools in its operations.

“This improves our efficiency of mold building, molding and customer communication,” says the company.

“We aim to become the best platform where our engineers appreciate their value, and the customer gets the best product and service for a solid value in terms of price.”
