PLAMO Co., Ltd.

We provide resin injection moldings with precision and strength as high as metal machining. 

We are a plastic injection molding manufacturer. We have established technologies for (1) making void-free thick plastic injection moldings (IMP manufacturing), and (2) resolving weak weld line problems that occur when resin contains fiber additives (IMM manufacturing). These technologies allow us to manufacture and sell high-precision plastic parts (such as medical parts where machining-level precision is required), and high-strength plastic parts for automobiles and other products. We can make brick-sized solid blocks with no holes from 25-kg injection molding material for provision as a modeling material for machining.

[Company strength]
Our company has made detailed proposals to enhance quality while reducing manufacturing costs in our work with customers in various industries as a development company. Customers are very pleased with these proposals. Our strength lies in the custom technologies that we developed for resolving issues with voids and welds in plastics. Our IMP manufacturing solves the issue of voids in thick products by re-shaping the injected resin through compression. IMM manufacturing crushes weld lines by changing the internal resin flow during injection, and then changes the fiber’s orientation to enhance the strength of the weld line. These technologies have been favorably received by our customers. This is because they enable high-precision molding, and solve the issue of low dimensional accuracy in irregular moldings with variable thickness. These technologies are used under an advanced quality control scheme. 

[Business description]
Our company is a plastic injection molding manufacturer that offers proposals to customers. We have a track record in producing high-precision, high strength parts. We can make use of our original IMP and IMM manufacturing technologies to make high-precision, high strength products that no other companies can imitate. Our company is regarded as Japan’s top manufacturer in the field of irregular molding (moldings with variable thickness). We are also No. 1 in Japan for weld line strength improvement and particularly for high-strength parts made from glass-fiber reinforced resin. We currently offer a service (IMP Block) in which injection molding materials are made into machining material (solid blocks). Production is managed under an advanced quality control scheme. You will have peace of mind while working with us. 

[Industry]
Plastic molding manufacturing

[Strength of products/technologies]
We will engage in a number of activities to exert our strength.
(1) Making manufacturing process proposals in the product development phase.
(2) Product design.
(3) Manufacturing and selling high-strength, high-precision products by using our original molding technology.
(4) Manufacturing and selling plastic blocks for use in modeling (IMP Blocks).
(5) Conducting low-cost, stable production through advanced production technologies. 
(6) Manufacturing reliable products in a stable manner through an advanced quality control scheme. 


[Representative's message]
Our company strives to remain a group of engineers in the plastic injection molding field. We develop original technologies, and reveal the outcomes in academic meetings, technology seminars, and industry journals. We manufacture plastic molding from start to finish, from product design to die and molding production. This means we can use both our accumulated technologies and theoretical technologies from the academic world in actual production, which makes us valuable to our customers. We will make your products under an advanced quality control scheme, and respond to various needs, including cost and delivery. I firmly believe that we are a company worth doing business with. Please do not hesitate to contact us.

[Company structure for market development/overseas expansion]
Our technology and sales departments serve as the point of contact for cultivating the domestic Japanese market as well as overseas expansion. 

[Market share/Ranking]
We are uncertain about our share in the injection molding parts market, but our IMP Block is the only service of its kind available in the world.
