What’s LWRT Mold?

As a leading LWRT Mold maker, we’re pleased to introduce new technology named LWRT for somebody else.

LWRT means Low weight reinforced thermoplastics. This type of material has been widely used in underbody shield of Automotive industry. both for Interior and exterior parts.

LWRT composite sheets are typically thermoformed into parts with a desired geometry.
Thermoforming is a stretch-forming process resulting in a reduction of the sheet’s original thickness. The deeper the cavity of the geometry is designed, the thinner the wall thickness of the final part will be.
The formability of the sheet material is its ability to form into parts with desired geometry without failure. The geometry of the parts varies according to different applications, and some
applications have a very complex geometric design. A good example of such applications is trunk trim, which has a deep-drawn, multi-cavity geometry.

The advantage of LWRT material would be:

1.weight reduction of at least 25% compared to traditional technologies

2.acoustic performance satisfaction without need for additional sound-absorbing elements to be welded or over-molded per piece.

MDC Mould, as a professional LWRT Mold maker, has produced many molds for our customers, such as Audi, BMW, Daimler, Jaguar, etc.

What are the advantages of parting surface design?

In order to make the product easy to eject and simplify the ejection system, the position of the parting surface should make the product leave the bottom mold after the mold is opened;

  1. Reduce the damage of flash to the appearance of the product, and at the same time facilitate the removal of flash;
  2. Facilitate mold manufacturing and mold parts processing;
  3. For products with high requirements for radial dimensional accuracy, the effect of flanging thickness on the product accuracy should be considered, and the vertical parting surface should be taken to ensure the radial accuracy of products;
  4. Ensure the strength of the product and avoid sharp angle and weak walls.

It is very important to design the parting surface. The parting design should be carried out at the initial stage of mold design to draw the parting design drawing, so as to ensure the smooth demoulding of the product and facilitate production.

What’s BMC Mould?

BMC mold is used a thermo plastic made up of a polymer resin, various inert fillers, fiber reinforcement, catalysts, stabilizers, and pigments that form a viscous. It is highly filled and reinforced with short fibers.

Depending on the end-use application, compounds are formulated to achieve tight dimensional control, flame resistance, high dielectric strength, corrosion and stain resistance and color stability. Its excellent flow characteristics make BMC mold well suited to a wide variety of applications requiring precision in detail and dimensions. The material is available in a wide variety of colors.

In addition, BMC mold is suitable for either compression molding or injection molding. Compressing molding of BMC is used to produce complex components such as electrical equipment, car components, housings for electrical appliances and tools, in large industrial volumes.

MDC Mould, as a professional BMC mold maker, is able to make BMC compression mold, as well as BMC injection mold with gate cutting.

What is GMT MOULD?

MDC specialized in compression moulds , GMT mould is one kind of them .

so what is is GMT ?

GMT is Glass Mat Reinforced Thermoplasitcs, a kind of sheet molding compound with fiber reinforced thermoplastic. It is produced on huge laminators, using a thermoplastic resin and one or more forms of reinforcement. The process yields a lightweight, partially consolidated, semifinished composite in sheet form. Most forms are produced to 1,300 mm to 1,400 mm widths. However, some newer forms are made to greater but proprietary widths. The sheet stock may be cut to size to suit placement in the tool for a specific application and also can incorporate a decorative or functional surface laminated to one side. GMT mould makes possible the production of large parts with low tooling costs and fast cycle times via compression molding. The potential for parts consolidation presents the opportunity to further reduce weight and cost.

What’s the advantage of GMT mould parts?

Utilization of regenerated、Low forming pressure、Long storage period、Short shaping cycle、High production efficiency

What’s the mostly application of GMT mold?

GMT mold is mostly used in Automotive and building&construction, chemical industry, packaging, sport equipment, etc.

Please keep in touch with us, when any doubts on GMT Mould.

Molding temperature of compression mould

The molding temperature depends on the curing system of the resin paste, the thickness of the product, the production efficiency, and the complexity of the structure of the product. The molding temperature must ensure the initiation of the curing system, the smooth progress of the crosslinking reaction, and complete curing.

In general, part having a large thickness should have a lower molding temperature than a thin-walled part, which prevents excessive heat produce heat build-up inside the thick part. If the thickness of the product is 25-32 mm, the molding temperature is 135-145 °C. Thinner part can be formed at 171 °C.

The increase of the molding temperature can shorten the corresponding curing time; conversely, when the molding temperature is lowered, the corresponding curing time needs to be extended. The molding temperature should be chosen between the fastest cure speed and the optimum molding conditions. It is generally believed that the SMC molding temperature is between 120 and 155 °C.

What is SMC Mould

SMC is sheet moulding.

SMC mould usually needs to use hydraulic press machine to produce parts. The cavity and core is fixed to top and bottom platens of machine. Once the material is placed into the open mould, the machine closes, mould gets heated, then the press pressure force material to flow all over the SMC mould. In the end, we can take the finished products from the mould.

SMC molding parts has good dimensional stability and excellent thermal resistance. So it is more and more widely used in heavy truck industry, bathroom, agri industry and other fields.

MDC mould, as a professional SMC mould manufacturer in Chian, provides the solution and proposal with our customers in the composite industry.
