The objective of this research were investigated for preparing a film of rubber for use in the spa business. It was a formula for the excellence of the film the study included the topic of different concentrations of latex a moment in the film to different concentrations of chitosan the effect of molecular weight of chitosan on the film the influence of solution pH on the film. And the spin speed homogenizer mixed with a suitable film forming. The stability of the film were under conditions simulating the relative humidity in the air. The preparation of films were mixing rate with a homogenizer to 1000 rpm the pH of the solution of chitosan is pH 5 the molecular weight of chitosan was 10000 KDa the concentration of chitosan was 0.1 percent in a solution of acitic acid at 2 percent and 25 percent concentration of the latex films are suitable for further development in the industrial.

The plastic outlet problem is a rigid inflexible material. When assembling with a metal outlet set then it is usually not completely homogeneous. When used The outlet burns out quite often. And the plastic itself is less heat resistant. This allows the plastic to melt burn easily and conform to the upgrade of technology capabilities in precision mold manufacturing. And high complexity The researcher has foreseen the factors in making Developing the design and manufacturing of rubber plug molds economic opportunities for Natural Rubber Applications Therefore came up with the idea to develop the design and material selection. And the factors that affect the production is the mold and the process of forming. To help entrepreneurs to exchange knowledge and study the knowledge from this research to continue in the application of natural rubber to increase future value. From the results and experiments it was found that the study of the method of creating a prototype compression molding kit by using rubber forming techniques can be applied and used by various components of forming rubber can be used to develop forming Rubber plug sockets are possible and this process can produce prototypes from natural rubber.
